yes they are free and you can get them by searching on google
Downloading with 100% safety is not possible but the Emulator-Zone is a good place.
Try www.emulator-zone.com or, www.coolrom.com or, www.rombomb.com
Yes there are various Pokemon channel emulators that are available for download. Some Pokemon channel emulators are available for free.
The android market has a number of good emulators, including fpse (playstation). The slide.me market has all the -droid emulators (gearoid, gameboid, psx4droid, etc.) There are some other emulators too, like a great N64 one by paulscode. You will need to google for this.
There aren't any out there that can be LEGALLY sold to you. You can download them for free at various sites and risk the chance of going to prison for the rest of your life. Emulators and ROMS are ILLEGAL.

No, but download znes and it is safe, small, and comes with free games.
Yes, it would be a good idea. Unfortunately, with the availability of emulators being pretty much free I don't think there would be much of a market for it. Sorry.
Emulators, known also as 'emus' allow software from other systems or platforms to operate on each other. Assuming you're asking about Playstation2, there were several free emus at: emulator-zone.com
