what if i give one code from humble bundle to someone ?

People do giveaways of just the codes all the time. I think you'll be fine

I'll call the internet police and they will put you in jail!!!!!

Each key gives you multiple games and if you already own one you don't get an extra copy. There are no consequences if you give your key to someone else though.

If you bought the deep silver bundle, you can't give only Saints Row The Third, you will also give all the games, because there is only one code for all the games this time.

Humble Bundle will send hitmen to kick down your door and confiscate all of your video games and donate them to charity.
