It sort of depends, but if the assault charge is still on your record, you will probably be denied by the TBI if you try to buy a gun in Tennessee. If so, you can appeal it, and it may or may not be overturned. Tennessee is one of only a couple of states that uses its own state system for gun purchases, instead of the federal system only like most other states, and they don't follow the exact federal protocol.
Arrested? Yes. Convicted? Not if the assault was a felony, or against a domestic partner.
If it's an ongoing felony charge, or a felony conviction, no.
If the possession charge was a felony, no, it is not legal to own or possess a gun.
No.
No, not in AZ or anywhere else.
