The Sanae on the left might be Yuuka, but I didn't see anything in the pixiv tags to show this.

By that logic, she can be any green haired touhou girl, she can even be Mima for all we know!

I think it's more likely to be Hina. But, yeah, like Neo X says, it could be almost anyone with green long hair.
(Note long, so Wriggle and Eiki are pretty much out of the question. Dai/Yuuka are almost out of the question too.)

Well, I was thinking of the ascot when I said "Yuuka".
