Yes. You can have a loaded gun in your own house or on your own probably basically anywhere in the U.S.
It depends on where you are and the circumstances. In the U.S. it depends on the state. Some states allow loaded guns with no permit, some don't, with the exception of when you are on your own property. Also, not every state has the exact same law. Depending on the circumstances, for example, in TN, possession of a loaded gun in public without a permit can be a misdemeanor or a felony, depending on whether you are charged with having a illegal weapn or intent to go armed.
It depends on where you are. In the U.S. at least, the laws differ from state to state...some states allow it, some don't unless you have a permit.
You can drive with any licensed driver
Yes. To be legal, it must be unloaded and inacessible. If you don't have a carry permit, the best place to store it is in the trunk, or if you don't have a trunk, as far to the rear of the car (away from anyone in the car) as you can put it. If you have a carry permit from any state in the U.S. you can carry it loaded and accessible. Tennessee recognizes permits from any state.
You can have it unloaded and inaccessible. In order to have it accessible and loaded, you must have a carry permit valid in Alabama.
Requires a concealed carry permit to do this.
in any state you must have a state issued drivers permit to register a vehicle.
Depends on state.
Yes, you have to have a minium of 38 hours of class time.
It depends on where in are, and exactly what you mean by the question. In most of the United States, there is no such thing as registration, so the term "registration" is irrelevant in regards to guns. But, to further answer the question, it may not be legal to have a loaded gun that is accessible in your car without a permit depending on what state you are in. In Tennessee for instance, you can only legally carry a loaded gun on your person or have it accessible in your car if you have a permit. You can, however, transport an unloaded pistol without a permit.
It depends on where you are. In the U.S. you can own a gun in any state without a permit, except that the state of Illinois requires an ID to purchase a gun.
