Sadly, no. you can only use Sonic, Shadow, and Silver.
Yes,but on the sonic & knuckles side,not sonic 3 side
I don't think it's in the Xbox Arcade, but I do know that you can play Sonic the Hedgehog 2 on a game called Sonic's Ultimate Genesis Collection. Sonic's UGC also has the original Sonic the Hedgehog, Sonic 3 and Knuckles, Sonic Spinball and a few more memorable games from the SEGA Genesis.
Sonic Generations is not ALL of the Sonic the Hedgehog games. The games represented in Sonic Generations for Xbox and PS3 are: Sonic the Hedgehog (Green Hill Zone), Sonic the Hedgehog 2 (Chemical Plant), Sonic & Knuckles (Sky Sanctuary), Sonic Adventure (Perfect Chaos & Speed Highway), Sonic Adventure 2 (City Escape), Sonic Heroes (Seaside Hill), Sonic the Hedgehog (2006) [Crisis City], Sonic Unleashed (Rooftop Run), and Sonic Colors (Planet Wisps). The 3DS version features different levels from the Sonic Series: Sonic the Hedgehog (Green Hill Zone), Sonic the Hedgehog 2 (Casino Night), Sonic & Knuckles (Mushroom Hill), Sonic Adventure (Emerald Coast), Sonic Adventure 2 (Radical Highway), Sonic Heroes (Water Palace and Special Stage), and Sonic Colors (Tropical Resort)
No it is not. Sonic the Hedgehog is on PS3 Shadow the Hedgehog is GameCube, Xbox, and PS2
Depends on which game you're talking about, but yes. Sonic 2, 3, Sonic & Knuckles, Sonic 3 & Knuckles, Sonic Adventure, Sonic Adventure 2, Sonic Adventure 2 Battle, Sonic Heroes, Sonic The Hedgehog (For Wii, XBox 360 and PS3), and most Sonic Games you can be. Usually, doing it requires the 7 Chaos Emeralds. However, in Sonic Adventure and Sonic Adventure 2, its' done as a special extra quest.

Solution 1 On "Sonic tedgehog mega collection plus" for the xbox, on sonic 2, 3, or sonic and knuckles you can go to a sound test and play all the music on the games.
