Please, Ray...there is only so much of your vast knowledge that us mere mortals can handle...

The fella sitting on what is probably a camera case might have a long lens in hand

Moving Right to Left,

the female looking person far right seems to be holding a sign...
the fella with his back to camera, seems to playing a baby grand...but could be some sort of console (like noise monitoring for an OB)
the fella with dark glasses watching the cars that have passed, seems to have a directional mic or flag available...OB sound pick up or yellow flag relay?
