"Awaiting Feedback" what does it mean ?

It means you/the creator didn't chosen yes or no on recivied gift.
First, the giveaway creators ethier contact you about the gift or email it themselves. Then, after they see accepcted the gift or not, they choose no or yes.
The winner(you), after getting the gift should attempt to redeem it, if it works, mark as gotten(yes), if not mark it as not gotten(no).

Did you click on the Gift-Symbol on the top, is there a link or key?

If I win a gift, when can I expect to receive it?

Giveaway creators are allowed one week to send the gift after the giveaway has ended. Depending on the type of gift and the giveaway creator, you might receive the gift to the e-mail address you have listed on the account page, a key might be added beside the gift you won, or the giveaway creator might have sent you a friend request on Steam to make the exchange. Please remain patient, and do not contact the giveaway creator during this time. If the gift is not received after one week, you can mark the gift as not received, and attempt to contact the giveaway creator on Steam to follow-up.

It just means you (the winner) has yet to click "Received" or "Not received" on this page, nothing else.

Check the won page regularly as the GA creator can add a key any time (and there is no further notification about it). And of course check your e-mail too, and if GA creator adds you as friend on Steam it is probably a good idea to accept.
Otherwise you just have to wait for now, the "not received" feedback becomes available after a week.
(And of course if you receive the gift you can and should mark it at "received" any time)
EDIT: I have a shitty connection, this page was nearly empty when I started to try sending this message :S

What might the game you won be, if I may ask?
