I is my understanding that Kids that are not in the high school program are not allowed to practice with the high school kids during scheduled practice. Now if kids want to come in and wrestle on their own with yonger kids then they can do that but high school coaches cannot coach kids in the wrestling room. The only other issue that comes into play is that if a kids wrestler is "practicing" with the high school wrestler and someone gets hurt it becomes a liability issue, depending on the circumstance. So the short answer to your question is no, you can't practice with the the higher schoolers during their practice, but yes you can wrestle with them on your own time.
