I counted seven and stopped after getting nothing but repeats for about 5-6 times (I think I did the quest about 20 times, based on number of prisms I've got). My list:

Kan-E-Senna and her bodyguard
E-Sumi-Yan and Khloe
Zhloe and Maisenta
Miounne and Geva
Beatin and Fufucha
Silvairre and Leih
Ywain and Nicoliaux

Beatin and Fufucha were hilarious (A+ whoever wrote the succulents line). After doing all the archer class quests, seeing Silvairre and Leih getting up to their usual nonsense was great. (Leih in that egg hat, though...)
