Aliasing girl_with_hair_over_one_eye_(k-on!) -> kinoshita_shizuka.
Aliasing girl_with_exchange_diary_(k-on!) -> chika_(k-on!).
Aliasing sasaki_(k-on!) -> sasaki_youko
Reason: Given recent episodes of K-ON!!, it looks like a lot of the classmates are getting confirmed due to the subtitles since several had a chance to speak (and there's also a few even get mentioned by name in the dialogue). The first appears to have her full name thanks to a comment from the director in the staff commentary (assuming from Vol. 1 extras) where her family name was mentioned and her seiyuu Kataoka Azusa's blog The others are directly from the closed captioning in ep. 18 as is the usual case.
