Just considering the story arc, Ophelia can end up in 4 different states, but there are an extra couple endings that give minor variations. Aida likewise has 6 different endings, but without the physical transformation; there are essentially 3 different emotional states she can end up in (WRT the relationship with her father). Lohannah and Camilla each have 2 endings, with the different decisions through the 3 parts of their story arcs moving them towards one ending or the other.
