Can i get some ID’s of these things on my rocks?

The first one’s stump me the most they are like a bubble/egg casing about 3-4mm in size.

Not sure on first three but the fourth is a feather duster worm harmless filter feeder. And the last one looks what could be a lightbulb anemone. I use the Tampa Bay Saltwater Hitchhiker page to ID a lot of things.
Edit: first couple of pictures might be tunicates or sponges.

thanks for your response i’ll checkout that page and sponges i didn’t think of that. tunicate seems possible

1st 3 are sponges, 3rd picture you might want to look at it closely it might be glass anemone
