You need something from them that releases their interest paid off/lein satisfied etc on their letterhead if a company, take that to dmv and they will send a new one in your name only.
NO
Yes. We call that "giving someone a car."
Do you have the title of the car in your name? Is there a loan on the car? You will have to register it if your name is on the title!
Porsche is someone's name. The car is named for the people who first made it
No

If only your name is on the title and the loan is not listed as a lien on that title then you are the legal owner. If someone else obtained a car loan for you then their name should be on the title to the car with yours. The question of ownership should be addressed if someone was kind enough to borrow money for you to have a car. The car should have full insurance coverage in case of an accident.
I believe the only ways to do it are to help design the car, or be of someone of great imprtance in society that someone wants to use your name. Or, Legally change your name to Koenigesgg.
Theft is not the same as accidents. If you drive a car, whether it is in your name or someone else's name, and you have an accident, then your own insurance is applicable, but if someone else's car is stolen, that doesn't seem to involve you. Presumably you were not in the car when it was stolen, right? What involvement do you have?
no
Car manufacturer
You can sell it immediately if it is your car titled in your name.
