Should I get lid of this rock or am I being paranoid becuz im a newby??

No. Don't panic. Those are all natural volunteers from the area the rock was harvested from. I seriously doubt there will be anything bad growing on it that you can't deal with. Be looking for pest anemones, like aptasia. Those you want to deal with right away.

Thank you, what do they look like, I have lots of different things on my rock

They come in different varieties, but they are all built like this.
