No you get PSP games on your PS3 at the PlayStation Store and then you move them to the PSP. The PSP will not play PS3 games, but the PS3 can download and store the PSP games and not play them
No you can't. PS Vita games can be downloaded and stored on the PS3, but you can not download the PS3 game on the Vita.
no as ps3 games are on a blue-ray disk and a ps2 does not have a blue-ray player
If the ps3 has backwards compatibility. The only ps3 system that will play a ps2 disk. (not a burned or copied disk) The 20gb and 60gb and 80gb will work. The ps2 system data is a download off of the play station store. This download won't work on the ps3 slim. I download the ps2 system data file off of the play station store. Then after I download the ps2 system data folder. I putted the ps2 disk (not copied or burned) in the ps3 slim and it didn't work. The only ps3 that will play a ps2 game has to have 4 usb ports. If the ps3 has 2 usb ports it won't work. Every ps3 model will play a ps1 game. If you have a ps2 a ps1 game will play on it. The 80gb ps3 doesn't play as many ps2 games as the 60 and 20gb ps3 do. The 20gb and 60gb play the most ps2 games.

PS3 games must be downloaded from the Playstation Store to work as a download on the PS3.
