First of all, it's Chaos Emeralds.
If you mean Sonic the Hedgehog (2006), there will be a stage near the end of the game called "End of the World" where you can be the other characters (Amy, Rouge, Knuckles, Tails, etc.) and find the Chaos Emeralds. They are very easy to find, really :)
It's the third installment of the Sonic the Hedgehog game series for the Sega Genesis. In Sonic the Hedgehog 3 you make your first encounter with Knuckles the Hedgehog and learn of the Master Emerald.
No, there are only 6 Chaos Emeralds available in the first Sonic the Hedgehog. Super Sonic's first appearance is Sonic the Hedgehog 2 when SEGA brought in another Chaos Emerald.
