You're making up laws and asking about them. Typically, the max gross vehicle combination weight permitted for interstate travel is 80,000 lbs. A single axle tractor pulling a set of doubles can do this.. in states which permit triples, it can have an even higher gross vehicle weight rating.
It also depends on your class of licence. If you have a regular Class C or D (depending on the state issuing it), you can operate any combination of vehicles up to 26,000 lbs. Gross Vehicle Weight Rating. With a Class B CDL, you can operate a combination of over 26,000 lbs. GVWR, so long as the vehicle in tow is rated at and is weighing less than 10,000 lbs. And a Class A CDL is required for combinations rated over 26,000 lbs. GVWR when the vehicle in tow is rated at over 10,000 lbs.
So long as the total weight rating of the combination is within the range specified by the class of licence you possess, and you're compliant with axle weight laws, you're good to go, generally.

Depends on the type and configuation. In the US, the max weight allowance for a single axle truck is 33,000 lbs. GVWR (some states will allow 35,000 for intrastate operation), while a tandem axle truck has a max GVWR of 54,000 lbs.
There's no such thing as a one axle truck. There has to be a minimum of two axles. "Single axle" if a term referring to a truck with only a single drive axle, and doesn't count the steer axle. Same with "tandem axle", "tri axle", "quad axle", and "quint axle".
You need to be more specific about the configuration. Is a single axle straight truck, a tandem axle straight truck, a tandem axle straight truck with additional lift axles, a tractor trailer...?
Well, that depends on what it's pulling. The federal law allows a max weight of 80,000 lbs., including for double trailers. Some states will allow a truck pulling doubles to gross 92,000 within that state. They can haul as much weight legally as a tandem axle tractor-trailer can, so long as they remain within legal axle weights.
Up to 20,000, IF the tires and axle are rated for it, and so long as the truck is within legal weight limits and bridge law formula.
Not enough information to answer. What type, is it a straight truck or tractor trailer, how many axles, what class vehicle, etc. would be needed to give you an answer. With weight laws in the US, a single drive axle truck rated at 26,000 lbs. gross vehicle weight could carry up to five tons, while a Class 7 single drive axle truck rated at 33,000 - 35,000 lbs. could carry up to eight tons. A tandem axle straight truck would be in the vicinity of 12 to 13 tons, and a standard, five axle, semi tractor and trailer can range from 23 to 25 tons of legal payload.

It would depend on the truck and the added weight should be placed ahead of the rear axle.
Which model? Which truck class (International makes trucks in Classes 5 through 8). Single axle? Tandem axle? There really isn't an "average" weight, because International's straight trucks are typically manufactured as cab and chassis, then any additional beds are added as aftermarket items.
