yes

You can choose 2 types of giveaways: Gift or Key. So yes, but check your inventory to see if it has regional restrictions before creating a giveaway.

As per the Steam FAQ “Extra Copies,” I believe you can. You will need to add the winner on Steam and send them the gift.

What will my friend receive when I send them my extra copy?
Your extra copy will arrive as a gift message.
