Is it right to choose who can be in a talent show and who cant in middle school when someone is trying to get over stage fright?

No, you should let them make the choice on their own but encourage them in their decision I think and encourage them to try new things even if their afraid\ of them like stage fright :) 
Hope this helped  at all :)

Always let the child make the decision
