hey i have some questions about this video for anyone who thinks they are an expert. is anyone willing to help me out?

i was just curious what the names of the people are that are in the video. (the anorexic girl, the skinny guy, the ** guys, the punk guy, the bald guy...ect.) does anyone know any of their names in real life? if not, do you know where i could find this out?
thanks!
