Here's a picture of some of the participants, courtesy of francefidele.fr:

So far, we have:
From +W left,
1 - Fr. Chazal (French, of course),
2 - one priest behind Fr. C.
3 - one in the front row,
4 - one in the back with the candlestick,
5 - Dom Tomas Aquino in front,
6 - a Benedictine just behind him, Fr. Bruno, OSB
7 - one apparently French priest in the back
8 - Fr. Pfeiffer
9 - and another French priest in front;
Then from +W to the right:
1 - one Dominican (has a hood?) in the middle,
2 - one tall priest in the back,
3 - Fr. Pierre Marie, O.P. in front,
4 - Fr. Marie-Dominique, O.P. smiling, just to the right of Fr. Pierre-Marie, O.P.
5 - Fr. Francois Pivert prayerfully folded hands, with one vote for bishop
6 - Fr. Hewko in the back with the candlestick,
7 - one taller priest in front with hands folded over his missal
8 - one priest in the back,
9 - and finally, the younger-looking one on the far right.
If anyone can fill in the names that would be great! You can use these numbers, just say Left#3, or Right#7.
I don't know which Number the priest is at Bishop Williamson's immediate right [that would be Right#1], but this again is Fr. De Merode, the new superior of the Priestly Union(SSPX) in France. I think he is later referred to on this thread as priest #5 even though priest #5 is Dom Tomas Aquino.

Dom Tomas Aquino is Left#5. You're saying Right#1 is Fr. de Merode. And Centroamerica assures us he's Left#3.
Okay! This is progress!
+W proceeding left:
Left#1 - Fr. Chazal
Left#2 - Fr. Faure (correct?)
Left#3 - (B from A thinks this is Fr. de Mérode, I say this is correct)
Left#4 - (B from A says this is Fr. Fuchs)
Left#5 - Dom Tomas Aquino
Left#6 - Fr. Bruno OSB
Left#7 - (B from A says it's
Fr. Rioult <-- Sermon «Les canonisations»
en Francais)*
Left#8 - Fr. Pfeiffer
Left#9 - (B from A says it's Fr. Pinaud)
*Fr. Rioult begins and ends his sermon on
« Les canonisations de jean XXIII et de Jean-Paul II » with a FLAWLESS Sign of the Cross in FRENCH! Do you people know how lucky you are to have a priest who provides for you
the spittin' image of the Curé d'Ars?!?!+W proceeding right:
Right#1 - (Centroamerica says this is Fr. de Mérode)
Right#2 - Fr. René Trincado
