I'm afraid we have to give up on getting that new job.
I'm afraid we have to give up you.

Are all the above samples right? If not, how to get them right? And why? Thanks.

Again, as I envision the idea you're trying to get across, all have similar meanings except the third one,

*I'm afraid we have to give up you.*

I'm afraid we have to give you up.

Here it means "surrender you to someone".
