Contrary to what many claim, there is not a federal law prohibiting it - the rules for keeping a gun in a semi truck are the same as they are for any other vehicle. You are responsible for knowing and heeding the laws of each state you're traveling in.
Yes, in accordance with the laws of the state(s) the driver is traveling through.
If you have a handgun carry permit, definitely. The handgun carry permit covers "any handgun that you legally own or posses."
The amount of tons a Mac truck can carry will depend on the size of the truck. A six wheel Mac truck with a dump can carry up to 30 tons or more. A Mac truck with 18 wheels and a semi trailer can carry up to 23 tons in the trailer.
The question can't be answered as asked. It depends on state laws, and laws are different in different states.

You call it a semi because it pulls a semi trailer.A semi is a type of trailer. A semi-trailer, as opposed to a full trailer, means it only has axles at the rear of the trailer and a full trailer has axles at the front and rear of the trailer. We call these in the UK "drags", as in wagon and drag, where the wagon that pulls the drag can carry a load on its own, whereas the semi-trailer truck, or tractor unit cannot carry anything without a trailer.
