Obviously just guessing based on assumptions, but I'd say the pink haired lady is 6w7-- most people auto guess 4 for alternative physical presentation but in my experience, 4 is more about refined aesthetics than rebellious aesthetics. Also, I'm not sure 4's would be the selfie posting type (taking maybe, posting would be few and far between, if at all.).
Helmet man is a little tougher, but I'd lean 3 or 7. Former is for the ear bling and the latter for the activity at hand.
