There is no Nintendo console that plays cartridges from all 3 of those console's games. However, you can download games from all three of those consoles from the Wii's Wii Shop Channel.
No the game cartridges are different shapes. Nor does the N64 OS support SNes games.
No they wont work on a SNES.

Nope. Regular Nintendo Entertainment System games (referring to 8-bit Nintendo/NES) are not compatible with the Super Nintendo Entertainment System (16-bit Super Nintendo/SNES).
A snes (Super Nintendo Entertainment System). The video game controller that is compatible with the snes.
A SNES (Super Nintendo entertainment system) emulator is what you would need.
The Nintendo 64 was named for its 64 bit CPU. In comparison the SNES was 16 bit and the NES was 8 bit. It is not the 3rd Nintendo game console, NES, SNES, Virtualboy, and Gameboy came out before it.
Nintendo SNES consoles can be purchased from game retailers such as Lukie Games. They can also be purchased from online mega-retailers such as eBay or Amazon.
Games for the SNES are very difficult to find - however for the best chance at finding the games you are looking for, eBay has SNES games at far lower prices than other retailers, such as Amazon.
NES, SNES, GBA, Gamecube, Nintendo DS, and Wii
Sorry you can't. Nintendo doesn't want anybody getting free virtual console games.
