Can anyone tell me what these 3 are and if good or bad?

Brittle sea star, Lil spikey Boi looks like an urchin maybe tuxedo. Unsure of the crab hopefully not the annoying aggro one (gorilla crab?)

 

[Glass Algae]

Adendum. Brittle star good. Tuxedo good. If the crab is the aggro crab he's not good. Sorry forgot to add that!

Brittle Star fish.. I have plenty of them. They are supposedly good. (Thats what I have heard)

Thanks everyone. The pencil urchin is so tiny. About the size a pencil eraser. I will throw the little crab!

The crab reminds me of a sally lightfoot I saw at my LFS

Put the crab in your sump. It'll do just fine eating whatever makes it down there.

Very cool looking brittle star. Great part of your CUC!

I got a common urchin about the same size maybe 25 years ago. It is now approaching softball size and happily blazes a trail around the tank every night scouring the rocks of algae. By far my favorite freebie ever!
