Yes. They are blunt and aggressive statements. Not a shred of politeness in any of them.

@the1000things Thanks for your supplementary comment.

They tend to be more blunt, but I would in certain contexts they are not. In North American English at least, "So what's your deal here?" could in certain circumstances--like when spoken in a friendly tone when meeting someone--would easily be interpreted as "what brings you here?/why are you here?" in a neutral, informal way. I can't remember the TV show, but I do recall a scene where two patients sitting alone in a hospital waiting room introduce themselves to one another politely, and one of the patients asks "So what's your deal?", the other patient then explaining her illness. Normally, though, it is indeed rather blunt and aggressive. As with many things in English, intonation is critical.
