(Left to right: 1 - 7)
#7 is definitely not Joanna. Joanna is a ginger-redhead with green eyes who parts her hair on the right, not the left. #7 is actually much closer to being a dolled up Maria with a slightly different hair style but I believe the hair color is too different (Maria is more of a dusky blonde) and her eyes seem lighter.
I don't think #3 is the new masturbating teacher as #3's hair is browner, the style is different, and she is not wearing glasses.
Unless there has been a massive change in Mrs. Turner, #5 can not be her. Mrs. Turner has red hair, wears a gray suit, and wears light colored glasses if she wears them at all. #5 is a much closer match to the new masturbating teacher.
#2 has a student / teeny-bopper look about her. Maybe she is a new YouTV groupie? She doesn't match any of the current four.
Of course, it would be easier to tell if most of the game images weren't lit like they were shot in the Batcave, and if there where any actual variance to the faces.
#1 is ms taylor, she has the same outfit, his images are done on Klub17, so that is the Marilyn outfit.
#2 she looks older to me, so no student , a teacher because she also is standing in front of a blackboard
#3 looks like she will be a gym teacher or athletic from the sports bra
#4 The nurse for sure, same outfit
#5 Mrs Turner, same outfit and in front of a blackboard
#6 she looks like maria, but all these women seem like they are the new school characters. so this might be the principle that Marcus and his dad fucked
#7 not sure but another cougar, it seems like these are all cougars and school related.
