These problems do not sound significant to me. That, coupled with no warranty means no lemon law case. BUT it is not unusual for dealers to do a bad job filling out the paperwork. If this is the case, your friend may have a remedy and get the same result anyhow. Also, if it is a buy here pay here place then starting January 1 of this year they HAVE to give a warranty. If this is the case, we should be able to help. Have your friend get in touch for a no fee document review. My office handles these kinds of matters statewide.
I would suggest calling a lawyer in your area. Scott Kaufman handles cases like these all the time so he can probably help you.
