Let's see... Lucario's trainer (can't remember his name), Latios, Ambertwo, Bulbasaurtwo, Charmandertwo, Squirtletwo, Dr. Yung, Dr. Fuji and all the other scientists that worked on Mewtwo, Lawnmower, Mirage Mew, Mirage Mewtwo, Hunter J and Cyrus all died properly.
Ash (x2), Pikachu, and Dariaki were all revived.
It's debatable if Spearow, Jessie, James, Brock, May, Max, Kidd, and Ash for a third time died, but if so all of them except Spearow were revived.
