My Grandpa and my step-Grandpa were Vatican 2 and did not show to have much if any Catholicity in them.

My Grandma (my dads mom) was part of Vatican 2.

My Grandma (my moms mom) died wearing the brown scapular but was  part of Vatican 2 even though my uncle is a Traditional Catholic and was living in the same house as my grandparents and was willing to drive them to a Traditional Catholic Church.

Am I as a Traditional Catholic suppose to pray for my dead relatives who did not appear to die in the Traditional Catholic Church?

I sometimes pray for my brother who died a few years ago. He was not religious at all, but sometimes I still pray for him even though I think he is most likely in hell.

We should pray for all the deceased. Unless you have a special revelation concerning the eternal loss of some one it is likely that they are in Purgatory.

It isn't likely.  It's unlikely.  Most people are damned, the saints unanimously say.  But it's the possibility of Purgatory that makes it imperative that we pray for our deceased relatives.  We have no idea who repented in their last moments and who didn't.  Better safe than sorry.  Better to act in the spirit of holy charity than be presumptuous.

My father was a fallen away Catholic.  I have zero idea if he repented in his last moments as he was unable to speak or communicate.  

Since no one in his family that is living is still Catholic, there is only me to pray for him.  It is both sad and wonderful.  I never miss a night.  

So pray for your loved ones.  You might be the only one praying for them.

I disagree with this completely. I think it is fine to pray for anyone who died but to say they are likely in purgatory seems false to me. I have read and seen in many traditional Catholic sources that most people are damned so if they are "likely" anywhere it is not purgatory but hell. Not to mention the fact that only Catholics can be saved and most people live their entire lives as non-Catholics. So unless there are billions of miraculous deathbed conversions it seems obvious that most people are damned.

There are many people in the Vatican II establishment who still have the faith.  Some saints have speculated that prayers said after a person's death can still be taken into account by God at the moment of death, since God is not bound in time; perhaps those prayers, seen by God from eternity, could win some graces for the soul at the moment of death.  So long as the person has received the Sacrament of Baptism, there's nothing to prevent God from giving graces of conversion even as someone lingers in between life and death, between consciousness and unconsciousness before passing away.

I too believe God may consider prayers for someone AFTER they have died. The following are prayers said by the priest and those attending when giving someone Extreme Unction.  They can also be found in the Pieta Prayerbook albeit missing the 3 Paters and Aves.

These would be wonderful to pray for everyone we know who has died THEN everyday for someone who is dying and has no one to pray for them.
We are told to store up our treasures in Heaven.  What a way to make friends !

Taken from the Rituale Romanum 1947

 Prayer to our Lord Jesus Christ, contemplating the various steps of His passion; to be said either by the dying or by another in his stead:
(This is the one time the church allows us to pray as if the prayers were actually prayed by another person.)

 We adore Thee O Christ, and we bless Thee.
 Because  by Thy holy cross Thou hast redeemed the world.

O God, in order to redeem the world, you willed to be born of a woman and to submit to circuмcision; to be repudiated by the Jєωs and betrayed with a kiss by the traitor, Judas; to be bound in chains and led like an innocent lamb to the slaughter; to be made a shameful spectacle before Annas, Caiaphas, Pilate, and Herod; to be accused by false witnesses, tortured by scourging and mockery, spat upon, crowned with thorns, whipped and struck with a reed, blindfolded, stripped of your garments, nailed to the cross and raised up on it, reckoned among robbers, your thirst slaked with vinegar and gall, your side pierced with a lance. Lord, by your holy sufferings, which I, unworthy as I am, recall to mind, and by your holy cross and death, deliver me (or if another says the prayer for the dying person: deliver your servant, N.) from the pains of hell, and lead me (him) (her) to Paradise, as you led the good thief who was crucified with you. We ask this of you who live and reign with the Father and the Holy Spirit forever and ever. All: Amen.

Three pious and helpful prayers for the dying together with the Our Father and Hail Mary, to be said during the last agony:

Lord, have mercy. Christ, have mercy. Lord, have mercy. Our Father, etc. Hail Mary, etc.

Lord Jesus Christ, by your sacred agony and by the prayer you offered for us on Mt. Olivet, when your sweat became like drops of blood trickling to the ground, I humbly implore you to offer up the flow of that bloody sweat which poured from you in frightful anguish. Present it to God, your almighty Father, in atonement for the many sins committed by your servant, N. Deliver him (her) in the hour of his (her) death from all the penalties and sufferings which he (she) fears his (her) sins have deserved. We ask this of you who live and reign with the Father and the Holy Spirit, God, forever and ever.

All: Amen.

Lord, have mercy. Christ, have mercy. Lord, have mercy. Our Father, etc. Hail Mary, etc.

Lord, Jesus Christ, who for our sake submitted to a shameful death on the cross, I humbly implore you to offer up all the bitter pain and suffering you endured on the cross for us wretched sinners, especially in the hour when your sacred soul left your sacred body. Present them to God, your almighty Father, for the soul of your servant N. Deliver him (her) in the hour of his (her) death from all the penalties and sufferings which he (she) fears his (her) sins have deserved. We ask this of you who live and reign with the Father and the Holy Spirit, God, forever and ever.

All: Amen.

Lord, have mercy. Christ, have mercy. Lord, have mercy. Our Father, etc. Hail Mary, etc.

Lord Jesus Christ, who spoke by the mouth of the prophet: "I love you with undying love; therefore I have pity on you and have drawn you to myself"; I humbly implore you to offer up for the soul of your servant, N., the very same charity which brought you down from heaven to earth, to endure all those bitter sufferings of yours. Present them to God, your almighty Father. Deliver him (her) from all the penalties and sufferings which he (she) fears his (her) sins have deserved, and save his (her) soul in this hour of his (her) departure. Open wide for him (her) the gate of life, and let him (her) rejoice with your saints in everlasting glory. Lord Jesus Christ, font of all mercy, who ransomed us with your precious blood, take pity on the soul of your servant, and graciously lead him (her) to the ever verdant beauty of Paradise. There may he (she) live united with you in inseparable love? never to be parted from you and your elect. We ask this of you who live and reign with the Father and the Holy Spirit, God, forever and ever.

All: Amen.

Praying for the dead is a good and holy thing.  

Quote from: Ladislaus

Some saints have speculated that prayers said after a person's death can still be taken into account by God at the moment of death, since God is not bound in time; ...

That sounds reasonable, although the person praying would have to believe the person was still likely alive.

I have known a person who took this wrongly and believed that he could pray for the conversion of his own father who had died many years ago.

I actually believe it in the latter sense.  We don't know what transpires between God and the soul when a person is dying.  It is quite possible that, at that last moment, God could look upon the many years of prayers to be offered in the FUTURE for that soul and grant some grace based on those prayers at the time of death.  God is not bound by time, and He can hear future prayers in the present; Our Lord suffered and died for all our future sins at the time of His Passion.
