1st two are cup corals.. IMO they are harmless filter feeders (but I do believe they have stinger cells) I have never had any issues with mine.

the other pic is aiptasia/majano (fat little bugger!) They are pest anemones and considered a nuisance. You can kill them by injecting with boiling water, lemon juice, vinegar or kalk (among many others)

The last two looks like a bubble tip anemone of some type and the first ones look like aptaisia or a plate coral?
