Well, he's invulnerable in the aspect of being a demon, and not being affected by their weaknesses, except for Iron.

Yeah, Lilith is above Alastair, frankly, although I'm sure he could severely harm her if he wanted, I mean what could Lilith do to him, he'd enjoys pain.

And Samhain is stronger than the rest of the demons that you mentioned, like Crowley, the Seven Deadly Sins.
