What is this?

Hi
I have a Nano that's only been up for a few months. Recently I've seen a few things growing out of the live rock. I'm sure it's been discussed here before but I have no idea what to search for to find the answer. I'm hoping someone can take a look and tell me what they are and if they're good or bad.
Also in the same picture, I found a worm today. I'm assuming it's a bristle worm. I did a lot of research on them tonight, but none of the bristle worms look quite like what I found. Would you guys also mind confirming that's what it is?
The second picture is the best. You can see the worm just under my shrimp. The growth I'm wondering about is at the base of the rock with tentacle looking things. I've seen a few of those in the tank. What are those and are they OK?
Thanks in advance for the help. I'm sorry if this has already been covered.
