You need to have the number displayed, and documentation of the validity of the DOT number.
should only need a dot number if it is used for a commercial purpose
If your vehicle is engaged in interstate commerce.
You need to be more specific. If it's for private use, is it a registered farm vehicle, recreational vehicle, or other vehicle exempt from classification as a commercial vehicle under FMCSR? In those cases, no, you don't. You might, however, be required to display "Not For Hire" on the sides of that vehicle.
There's no logo requirement on a commercial vehicle. On a Class 8 tractor--a semi--you need the license plate (base plate) and either a DOT number or "not for hire." You can put "not for hire" on a truck that is not used in commerce, like the tractor that pulls a race team's trailer. Everyone else must have a DOT number. But as far as logos go, you don't need to have a logo on your truck.
You only need a DOT number if you own and operate a Big Truck. INCORRECT! If you're in the transportation business period, you need either a USDOT number, or, for an intrastate only operation, a state DOT exemption number. It is not limited to just large vehicles - a company such as Hertz, which rents out passenger cars, is also required to have a USDOT number.
A closed dot includes the number, an open dot excludes the number. Greater than excludes the number, so it would have an open dot.
If the vehicle doesn't require a CDL and the vehicle is registered in that state, no. If the vehicle requires a CDL, yes. Vehicles falling under exemptions such as the farm truck exemption or emergency vehicle exemption vary by state.

Yes. However, whether or not you're able to pass a DOT physical and obtain a DOT medical card (which you'll need in order to operate a commercial vehicle) will depend on how severe your condition is.
Yes anytime your driving a vehicle that requires a health card you need to have your health card with you
