No, not unless the firearm has been "de-milled"- permanently changed to prevent it from firing. That usually means cutting the frame into 3 pieces with a cutting torch.
No
You can't really "check online" but if you qualify to own a firearm anywhere in the U.S. you can own one in Florida. Basically, you have to be a non-felon and have disqualifying misdemeanors.

No. A felon cannot live in the same house as a firearm. One of them has to go, or both of you may be prosecuted. Actually, that is not exactly correct. A felon cannot have access to a firearm (or more specifically, cannot have constructive possession). Constructive possession is loosely defined, based on several state and federal court cases, as having access and intent to possess an item, in this case, a firearm. So, if a felon lives with a non felon, the non felon can own and possess a firearm as long as the felon does not have access to it. This basically means that the non felon would have to keep the gun locked up at any times he or she does not have personal control over the gun.
