You can not sell the games you have already activated in your steam account. If it's in your library it won't get out of there.
You can trade steam keys if they have not been used before. I have Deponia but I saw that all of the games you were offering are already activated in your account and wanted to warn you that you can't sell already activated games ( A lot of people think they can exchange the games in their library)
