I'm assuming you're referring to the Freightliner FL50/60/70/80/90 or Freightliner M2, both of which have been marketed with the "Business Class" trim package.
What it really amounts to is the Gross Vehicle Weight Rating of the vehicle. If it's 26,001 lbs. or higher GVWR, then yes. If not, then no, unless it's either hauling hazardous materials, or is a bus designed to transport more than 15 persons (including the driver).
Yes. You can drive that vehicle with either a Class B or Class A CDL.
Depends. You can drive up to a Class 6 truck (up to 26,000 lbs. GVWR) without a CDL. Class 7 or Class 8 trucks require a CDL.
You will need a Comercial Class Drivers License. This is usually a Class A CDL in most States. So you will need CDL training.
Yes, you would. Without the trailer, you could operate it with either a Class A or Class B CDL.
You would need a Class A CDL for Dump Truck. It's not as intense as more restrictive classes of CDL.
To drive a cement truck legally, you need a class B CDL (Commercial Drivers License). At 18, you can apply for a class B CDL.
Depends on which Class of CDL. A driver with a Class C CDL is not licensed on that vehicle. A driver with a Class B CDL can drive that combination only if the GVW of the trailer is less than 10,000 lbs. A driver with a Class A CDL can drive it.

As far as I can tell, the C70 has a Gross Vehicle Weight Rating in excess of 26,000 lbs., meaning you would need a Class B CDL to drive it as a single vehicle.
Yes.....
Yes.
