You probably really like Who's answer, but it's dead wrong so don't act on it.
You might get out of some of the charges, because five tickets for expired registration is a bit much, but not all of them. I speak legal-ese fluently, and even I couldn't understand all that abbreviated gibberish you typed. Just speak English next time. Anyway...
The charge is driving with an invalid registration, and you were driving. The "I didn't know" excuse doesn't fly in court, because it's your responsibility to know how the law works. The charge is driving with invalid tags. Not owning, driving. And yes, yes you are expected to make sure the vehicle you're driving is legal for public roads. That means registration / tags and insurance have to be valid, and you have to be able to prove it on the spot.
If you got charged with driving under a suspended licence, that's got nothing to do with your buddy. Drivers don't get charged for someone else's suspended licence, only their own licence. If that was one of the charges you tried to type out, you're not getting a free pass on that one either.
Hire a traffic ticket defender or lawyer for this, and you'll probably have a few of the charges reduced or dropped. Ticket defenders are usually ex cops and / or paralegals who know the traffic court system, and you really do want one. You're thinking the "it's not my car" and the "I didn't know" excuses are a valid defence, and they're not. Don't do this on your own, hire professional help.
