It's pretty clear that they're the trapped demons, because the great red bloody shrine is for Diablo, who is the greatest of them, the true question is which of the great demons (Greater or Lesser) are the ones that are shown in the cinematics. I'm really sure about this is the Black Soulstone because it was said by one of the developers that they wanted to show in only one cinematic the Black Soulstone from the inside and at the same time the Arreat Crater

I support the idea that the one in the middle might be Baal, because of the horns pointing backwards, and of course the red one is Diablo, but the one with "wings" (?) in his head, I'm confused :S
