No, if that’s real gulf LR it’s a lightbulb anemone ..
Yes, TBS live rock. Any idea on the white crab?
I’m not a crab expert….But don’t think it’s a gorilla crab… could be wrong
Looks like a type of emerald crab
Looks like mithrax crab and Majano anemone - Pics a little fuzzy
Red Cling Crab?
Gorillas usually have black tipped claws. Considered bad pests. Very common on Gulf of Mexico rock.
Not a Majano
What’s that top pic? Are there a bunch of anemones in that cave?

#1 looks like a gorilla. Can trap them with baited bottles.
#2 @OldRed1 has one that looks a bit like that, I think.
#3 ¯\_(ツ)_/¯

In general, it is not easy to ID a crab, other than the species that are commensal to coral, or very few specific crabs. Other than these, most of the crabs are not reef safe. There are herbivore crabs that are good reef cleaner and reef safe. I use this rule:
If a crab has pointy pinchers, it cannot live in my tank. If the pinchers are spoon tipped, they can stay.
Pictures below (not my pictures) are examples of my criteria:
Reef safe pinchers
Not reef safe pinchers

Yeah, that looks similar to our box crab! It’s a diverse set of crabs, so hard to tell from this single picture.
OP, have any other photos?
Also, #3 is likely a lightbulb anemone. I have one that’s a chonker in my tank. Should be safe, more so a matter of appearance as to whether it fits your style in the tank.
Yeah, I have other...equally bad pics. Pretty confident the first is a gorilla living in that hole, super hairy one at that. He stays pretty close to that rock, in the hole or under the edge. To do any better, I think I'll have to catch him. Though pretty sure I dont want him in there anyway, so if I catch him, that will be the end.
The second crab has been hanging out on the VCA nozzle that fell off and floated to the corner of the tank. its mostly white, no real markings. I am assuming long term, I don't want it in there either.
The anemone, just wanted to make sure I shouldn't be shooting him up with some Joe's Juice...

A variety of crabs come with live rock, the fresher the live rock, the more crabs are on it. I would use a baited tall glass to trap them. Only the bad crabs will go into this trap since the good ones are herbivore.
Kill that anemone early or you will be sorry.
It’s a lightbulb anemone they do not reproduce in an invasive way.

I got my rock from the Gulf of Mexico too. These anemone behave just like the normal Aptasia, multiply like crazy, sting coral and clams like crazy and need biological or tedious manual control.
Pics are quite fuzzy. The bulbs I see discounts aptasia but can be.
