Question

The courtroom and trial: Identify a courtroom in your area or state. Identify those who
work in a courtroom and describe their roles

Answer 1

This is a question that we can not answer. We don't live in your area or state; therefore we would know who works in your courts. You need to check your town/city for a local court. Then you need to go down there and find out who works there. Then it would be very interesting for you to make an appointment to interview one of the people who works there about what they do.
We will be happy to make further suggestions if you wish to repost after you have done some of this research.
