To my knowledge, only if you have a permit you can.
It depends on where you are. Here in Tennessee, nothing is required other than some form of ID, but the pawn shop will probably run a stolen firearms check on it.
Florida does not require handgun registration, so the answer is, you don't. If you are referring to a permit to carry, check with a local gun range. They should be able to tell you how to go about it.
You don't. in Florida, as well as most other U.S. states, there is no such thing as registration.
Go to the nearest police station. Actually, the answer is, you don't. The state of Florida does not require handgun registration.
