Edit: I read your question again and I might have misunderstood it when I replied (below). If you want to duplicate a call-out view to create new views then yes you can copy paste.
Original reply (ignore it): Yes you can show the original call-outs in other views. But DO NOT copy paste because that will duplicate the actual call-out views, not just the symbols. What you should be doing is open the other view, create call-out but you must tick Reference Other View box before draw the call-out boundary, then you can choose the original call-out view from the view list instead of create a new view.
