Doesn't look like one to me more like a porcelain crab

That's a red Mithrax crab - a Ruby Crab (the red version of the Emerald Crab).

Then is this a gorilla crab? Doesn't look like the same crab.

Different crabs for sure - this one is most likely not reef-safe, but could you get closer up pics of it?

I lost track of it. They are in a bucket but here is another one.

This one I would guess is a Mud Crab of some variety (taxonomic family Panopeidae).

Edit: This one is likely not reef-safe, but these crabs tend to stay small, so the damage they can do is generally pretty limited.

This one's a red mithrax - about as reef-safe as true crabs (brachyurans) get, but it may cause problems particularly once it's full grown.

This one is a decorator crab of some kind; not particularly dangerous for fish/inverts, but they like to take pieces out of things (like sponges, tunicates, macroalgae, and corals, to name a few) and use them for camouflage - so they're more reef-safe-with-caution.

The last crab I found was bigger than all the others and hairy, but didn't see black claw tips. This one safe too?

Can you get a pic of it's back/topside (dorsal side)? It's hard to tell the body shape of the crab from the pic.

Where are all these crabs coming from?

 

[ISpeakForTheSeas]

That's a Pilumnus species crab, and it seems to be female - not reef-safe; you could make the arguement that it's a gorilla crab:

Yeah, gorilla crab is a bit if a catch-all term in the hobby for not reef-safe, typically hairy crabs (technically, the term applies to Xanthid crabs and arguably Pilumnid crabs, but that's sort of irrelevant

Where are all these crabs coming from?

From the 50 lbs. live rocks I just received today from KPA. This is all the hitchhikers I caught.
