Help me ID again please?

[Oceanic Wrath]

Sorry to bother everyone again so quickly |D
But I have a few guys I'd like to ID for my books. They came in on my live rock I adopted :P (I adopted the clown fish I mean)


There's a few of each in my tank, I just want to be sure they are good for my aquarium and so I can ID them in my aquarium notebook I keep. They are all small, but better safe than sorry~!
