Where does downloaded software from synaptic get saved so that I can have a backup and give it to my friends..

I'm not really sure here, but I always believed they where just installed. Sure, there will be temporary files, but I think part of the installation process is to clean this up.
Anyways, they can always install it from their own synaptic as it is available to all ubuntu-users.

For other distributions there will be other repositories, and for other OS, there will be other sources.

I believe programs are stored in /usr, but you should confirm that.

And you can't just "give" programs like that. There are loads of stuff like dependencies, settings, etc that need to be transferred as well. Its really not worth it IMO. Just ask them to redownload the programs.

/var/cache/apt/archives/

And to clean them up, use

sudo apt-get clean
