If I have a reservation for 10, can I bring more people than 10? Or do I have to edit that online? How do a I do that? Can I do that? Is that okay?

When going with a large party, you will always be recieved better by giving the actual number. They generally have to prepare a spot to accommodate so many...

I think they will accommodate, but a call for heads up would help a lot.

They have always been extremely accommodating for us in the past, but i would suggest to call them to make sure theres no confusion.
