I think it would be Angel, Archangel and then Principality. If you do want to remain a Third Sphere Angel that is.

It's not like there is a specific amount of times an Heteromorphic being can evolve. It seems Demiurge only evolved once, from Imp to ArchDevil, and Cocytus from Insect Fighter to Vermin Lord as well. Likewise, I imagine you can evolve more than twice as well, since WN Ainz went from Skeleton Mage, to Elder Lich, to Overlord and finally Demi-Lich.
