First pic aiptasia anemone, they are pest and can multiply easily. For me peppermint shirmp was the solution, third pic can be a feather duster worm( reef same) but I not sure.

Should I keep the first one. I'm new and I night these live rock and the corals were on them. Had no idea

I get rid of my aptasia by taking the rock out puting a flame to them. Some people use peppermint shrimp or berghi nudibrach to get rid of them.
