I see several characters that aren't marked on the picture (but maybe tagged).
Fate/Strange Fake's Assassin (purple hood, girl next the other Assassins). Aoi Toosaka next to her husband. Shirley besides Kiritsugu. The other Rin Toosaka from Fate/Extra.
Everyone should be labeled now, and I added a couple of tags. (The old priest is Risei Kotomine, for the record.) By the way, since Kotomine's wife recently had her name revealed, I went ahead and updated her note to reflect this.
Edit: Also, I'm reasonable certain the person marked as Emiya Norikata is actually Issei, so I went ahead and changed that.
