Tier 1: Slimes

Tier 2: Insect Girls

Tier 3: Beast Men

Tier 4: Demons (Succubi and their subspecies, including corrupted demihumans)

Tier 5: High Monsters (Dragons and other great beasts, like Chimera and Manticores)

Tier 6: Divines (angels, demigods, gods, Chaos Demons corrupted or otherwise)

This probably works for terms of power and hierarchy, save maybe Succubi have more political pull in areas around the Demon Realm.
