1st picture looks like a polyp of some sort ,second one maybe a tube anenome, 3rd and 4th are xenia and the last one looks like a sea squirt.

The first pic reminds me of a baby goniopora, I agree with the xenia ones and the last could be maybe a tunicate of some type? Not sure about #2

goniopora, maybe turbanaria (?)
barnicle
anthelia or gorgonian (briareum)

cheers for the suggestions. the last one unfortunately looks like its been nipped of today, its just a pink stump now do you think it will regrow? the second one has thoughts filaments but it has some appendages that come out of the middle and pick bits from the filaments they look bit like tiny elephants trunks. it has a number of other appendages much shorter protruding from the very center. i have noticed a small crustacean hiding in a crevice all i can see is legs with feather like parts filtering the water. unfortunately not able to get pick

The second photograph shows the setae and feeding tentacles of a polychaete worm in the family Flabelligeridae. They live in burrows or crevices inside the rock. Using the tentacles they spread a mucus net over the setae to collect food particles from the water.
