Hitchhiker ID pls

Hi I bought a bunch of liverock few weeks ago and was just wondering what some of these things I found on them are: 1) Not sure if it’s some sort of shrimp or amphipod? 2) a brown/purple ball there’s a few of them scattered around 3) some sort of white thing growing? Can’t find any information about it anywhere

Would appreciate any information on the ID of these things thanks

Number three is a very cool white sponge.

Number one looks like it might be a shrimp I think they are called skeleton shrimp?

Hi il be honest I’ve only seen it once it just hides in the rocks but I don’t think it looks like either of those
