So I'm assuming Chie is the age she should be in 2005 or so as a school councilor in the Geshiken universe (~30 years old).
She seems to be a young adult in 1995 for Evangelion (~20 years old).
She looks like a middle school student in ~1985 for Urusei Yatsura (~10).
In the third panel she looks to be about ~5, which would be ~1980 which is the end of "Space Battleship Yamamoto", and I think Oono is cosplaying as Mori Yuki from that series (see her posts on Danbooru & the figure with the belt posted here:http://www.dannychoo.com/images/photo/blogg_thumbs/1690.jpg .
The last panel is Chie as a baby, which must be at age ~0 and year ~1975. Being as Urusei Yatsura is well before my time, I haven't got a clue what was popular then or who Oono might be cosplaying there.
