What exactly is a "mini-Peterbilt", may I ask? If you're referring to pickup trucks with aftermarket bodies designed to look like Class 8 trucks, then no, you don't need a CDL for that.
If the vehicle requires a CDL in service, it'll require a CDL for the test drive.
Yes, you will need insurance to drive with a CDL license.
You can drive vehicles which require the operator to possess a CDL....
A CDL license is required to drive a skid loader. Many employers will require a CDL to get positions that require the operation of a skid loader.
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.
Your CDL permit is in addition to the class of licence you had beforehand. So long as you were licenced to drive a car before you got your CDL permit, you can drive your own car while you possess a CDL permit.
Up to 15 passengers (including the driver). Anything more requires a CDL and passenger endorsement.
