Friend or foe

Hi, I found these on my recently acquired live rock.

I would appreciate your advise in terms of if I can leave it or if I shall take any procedure to remove it.

Can you see what it looks like a white bag with a blue mouth? (Under the rock)

This one changes shape, sometimes is plain others is round, and seems to move around.

This one moves around. Seems to like the light

This rock with anemone look like from Pacific Reef. 

I like your topic HAHA. I think is neutral if you like anemone around your tank.

The white bag with blue mouth - any tentacles? If no it might be some kind of tunicate. If so, that's ok. Tunicates are filter feeders.

the white thing sticking out of your LR - can't tell what it is too haha, my hyperactive imagination suggests it's a barnacle 

the brown polyp - should be some sort of paly. That's ok

the green anemone that likes light - that should be a majano. They are a rather interesting addition as long as you monitor their population

This one is also moving around. I only spot it at night with lights off

Looks like a chiton. Harmless.
