Hi Matt-Nii! welcome to Deviantart,
They're from a few different companies:

Kade is a Iplehouse Jessica head [usually a female doll] with an AoD body
Hiei is a B&G Afra head with a CustomHouse body
Owen is a Migidoll Ryu with an AoD body

I have two others from Luts that I will be posting pictures of later.
If there's anything else you're curious about feel free to ask. ^^
