In my world there are 8 primary elements, which have an elemental avatar, and also represent a different part of the mortal being. I'm fairly happy with it, but I'm always open to feedback or differing perspectives.
1. Earth- Chenoo(North American Rock spirits)- Bone
2.Air-Sylph- Breath
3.Fire- Salamander-Flesh
4.Water-Voldyoni/Rusalka-Blood
5.Plant-Nymph-Emotion
6.Animal-Satyr-Instinct
7.Metal-Gremlin-Will
8.Void/Aethyr-Boggart-Thought
The Void in this instance isn't the gaping vacuum of nothingness, but the endless chaos that existed at the beginning of Creation, and still roils beneath the surface driving all the realities forward.
