These would normally go in C:\Users\(YOUR_USERNAME)\AppData\LocalLow\Owlcat Games\Pathfinder Wrath Of The Righteous
Make a backup of that folder first if you already have custom portraits.
These portraits are mostly spellcasters and elementalists. There is a focus on dwarves and some asian people, orcs. Of course it's a pretty varied pack overall and the portraits are not uber-prototypical so many can stand in for different species/classes. They can be shamans, witches, sorcerers, druids, etc.
I don't know if these work in Kingmaker, only played Wrath, but if they use the same portrait system, they will.
