That's a very vague question. Having a firearm where? Home? Car? Work? Transporting it while travelling? Carrying it loaded? Besides all that, in the United States, laws vary from state to state, so there is no real way to answer the question as asked. If you will rephrase the question and be more specific, we can answer the question.

The four primary rules of firearm safety are: Treat every firearm as if it is loaded. Never point the muzzle at anything you are not willing to destroy. Keep your finger off the trigger until you are ready to shoot. Be sure of your target and what is beyond it.

Not enough information to answer. If you were CONVICTED of a felony, you are disqualified from possessing a firearm- period. You have not said if you were convicetd, or whether it was a misdemeanor or felony.
Having a magazine in a firearm can mean that the firearm is loaded, and ready for use (if a cartridge has been chambered). If it is not loaded, it takes longer to put it in a condition that it can be fired.
