The one from 17 I think is not supported yet I have gone to the mansion a few times at that time (noon I think) but nothing happens, but about the phone you have to take it to melissa (the hot goth from school) and she´ll try to hack it.
Couldn´t really tell you, if you enter that room by the secrect passage (where the maid is tied) you can have 17 wash you and jerk you off, but it seems like that is not the event since is still showing ¯\_(ツ)_/¯
You must do the board game with the girls (you need to lose it, which is not hard for some reason 😂) and then you can try to call Chloe in your bedroom next time when she is with Dana.
