I was looking through the list and screenshots, both here and on the website... nice compilation! It's nice to finally see them at more than one angle. Some comments...
#5 and #11 for female are both called Longhair, though they are different. #5 can be called "Longhair Styled" while #11 can be "Longhair Unstyled". #5 definitely looks more polished while #11 is more plain. Or perhaps, based on that last sentence, "Longhair Polished" and "Longhair Plain"?
#12 male is currently called Beach Style. I agree, however "Surfer" might be better?
#19 male, which is currently unnamed, reminds me of John Travolta in the movie Grease. Perhaps call that style "Greaser"? His character in the movie was a greaser, as were all his friends who constantly combed goop into their hair to slick it back while doing something stylish with the front, sometimes pointy. If you search "greaser" in Google images you can see various examples.
