The regulations depend on the state. In Wisconsin, if you have a permit to hunt and have taken the hunters safety course and are at least 14 at the start of the season, you can hunt alone. the youth hunt in my state is a bonus day. As far as the amount of deer taken, that depends on the amount of tags you have. You cant kill an animal you don't have a tag to put on. I would check with the people who offered your hunter safety course or call your local DNR office.
Good luck, hope this helped.
