In my headcanon Robin left Storybrooke at some point and went and studied in another realm where time goes faster (maybe Zelena went with her but she didn't visibly age).

Speaking of Alice, I think the 7x07 flashback is set shortly before the curse is enacted and NEF was frozen in time because of Cora's bubble, explaining why she hasn't aged.
