What is the difference between braze-on and clamp-on derailleur?

A clamp-on has a metal clamp that wraps around the tube of a frame that does not have a built-in mounting tab for the front derailleur. Braze-on derailleurs can be mounted to frames that do not have a mounting tab, using an adapter.

How do I know what size my FD clamp is?

Simplest way is to wrap a bit of paper round the tube and mark where it meets. Open the paper out and use a ruler / tape measure to measure the distance between your marks – that’s the circumference of the tube. Divide by Pi (3.14159) to get the diameter.
