In my own universe, I see the Predators as we have people on earth....hear me out.
On earth we are separated by countries/states. I imagine Predators are separated by planets, moons, whatever have you (As I see multiple Predator worlds and then being more expansive).
None two Clans are alike, maybe similar, but not exactly the same. I imagine there are large clans, almost like empires with their own caste system as we saw in AVP. There are probably loners, small clans (P2), misfits (Predators), and a variety of other Yautja - Some being Rebels (BadBloods or Space Pirates).
The point is I believe all these options exist simultaneously and they aren't subject to one homeworld but rather a complex Yautja society all varying from each other, much as the people of this planet are all human but none two cultures are exactly alike and even deeper than that, within a specific culture none two persons are alike either--same goes for (my interpretation) Yautja.
