Of course not.
No
No, there is no such requirement for commercial vehicles in any state.

If a CDL driver does not pass the written air brakes test and conduct their road test in an air brake equipped vehicle, they get a restriction prohibiting them from operating an air brake equipped commercial vehicles. However, this is only applicable to commercial vehicles - operating a non-commercial vehicle with air brakes requires absolutely no qualification, whatsoever.
No. Whether a vehicle has air brakes or not doesn't determine if a CDL is required for it, and it is possible to have a CDL with a restriction prohibiting the operator from driving air brake-equipped commercial vehicles.
There is no such requirement. According to the FMCSA, a Commercial Motor Vehicle is defined as being in commercial in nature, and having a Gross Vehicle Weight Rating of 10,001 lbs. and higher. So most 1 ton pickups fit this guideline when they're used for commercial purposes, and those don't have air brakes.
