Hi all. :D I'm new to the hobby and just started my tank about 2 weeks ago, and now that their is stuff growing on the live rock, and I can't really figure out what they were, I was wondering if I could have some help IDing them. Also, if you notice anything else please let me know!

(sorry for the pixelation. My computer is stupid, apparently)
a. Some kind of tube worm? It looks like a little red button, and sometimes it is down into the tube and sometimes near the top as in this picture. Just small and red, no feathers. Any idea?
b.- green algae stuff- is this hair algae and should I remove it?
c. Some kind of coral, looking for help with care. See pic 3, as again this pic isn't the best

Another, clearer pic.

These little guys- I seem to have about 3 clumps on the live rock, I figured they were dead when I got the rock but just started to notice little feelers the past few days. They are very bleached- is there any way to save them??
Thanks in advance!!!!!!

A. don't know.
B. sponge? There could be nuisance algae around it. But the spikes look like ball sponge spikes.
C. Cup coral. I would try to feed little meaty items directly.

Sweet guys, thanks! If anyone knows what the tube thing is, let me know. :D
Fed the little corals frozen brine shrimp with a baster, and it seemed to stick on a few of them!
Any more recommendations or comments are as always appreciated!
