Yes, but as far as I know you have to make them yourselves.

Custom songs are songs that Guitar Hero player across the world cerate in the Guitar hero studio. They make their own tunes and let others play and listen. Any one who has a Guitar Hero game with the studio in it can do it.
You can add your own custom songs to Guitar Hero World Tour. You cannot create custom songs through the game however.
you cant custom songs with out buying them and why play guitar hero 5 that game is horrible
no you can not ONLY in guitar hero WORLD TOUR.
Yes
You have to have internet access at home and connect you xbox. In the market place from the xbox you can search guitar hero 3 downloads
Yes
If by guitar hero 4 you mean world tour the answer is yes. go into the xbox live marketplace and look around.
You burn the songs from the guitar hero 3 to a x-box 360 memory card. <<< That makes no sense idiot, we want songs onto the game that are not arleady on there so why would we burn songs from guitar hero 3 onto the xbox? I don't think you can add your own song to guitar hero.Im pretty sure you can't but I might be wrong.
lolz ill kill you
yes
As you have Guitar Hero 3 on the PS2, you aren't able to get custom songs, however, if you have guitar hero 2, you are able to put the disk (assuming it's a proper copy) and in your computer. Youtube can help with this, but you can use "scorehero". Look that up on google. :)
