Consoles -> Color TV Game, Famicom (NES), Super Famicom (SNES), N64, Gamecube, Wii, Wii U Handhelds -> Game and Watch, Game Boy (+ Pocket variant), Gameboy Color, GBA (+ Micro and SP variants) Virtual Boy, DS, DS lite, DSi, DSi XL, 3DS, 3DS XL.
No the game cartridges are different shapes. Nor does the N64 OS support SNes games.
No.
You don't. You have to obtain and use a SNES console.

No. While it is technically possible, Nintendo (or anyone else for that matter) have not released an adapter to allow this. There is a new console out now called the FC Twin that has slots for both NES and SNES and can play both. Hope this helps.
