Can you roller skate in the park

Yes, you can

Of course

Yes! There is a small rink.

Yes. There are some good sidewalks and paved trails. They also have a little skate park (all flat, fenced in) for kids.

Yes

I have seen people on roller blades, but don't know if any actual rules for skating. I do know that Bill Baggs park has some nice places to bike, walk, jog and roller blade. I would say go for it. Have fun. I dont think you will have any problems.
