Are you serious with this question? No, the registered "Keeper" owner will get the bills in the mail or online. First, why would you want to insure a car twice and pay twice the bills for the same vehicle? Second, unless you own the car I doubt if you can insure it. You can pay the insurance bill if you wish but unless the car is registered in your name the bills and responsibility will go to the registered owner. Now it is NOT a good idea to provide insurance on anybodys vehicles except your own or/and your spouses.
You should pay tax to the state that you are getting your car registered to
If it is registered, yes. The MVD determines the value.
Yes.

You pay sales tax to the State in which the vehicle will be registered.
The ticket will be sent to the owner because the car is registered to him/her. If the driver of the car won't pay for it, you can take him/her to court and force him to pay the fine.
You don't pay for the plate, but the registering of the car. The DMV sends the plate and tags when the car is registered with them. Then, each year you pay for new tags.
