If we're going by Archie 'verse Sonic, Sonic on Chaos Emeralds is Super Sonic, Knuckles is Hyper Knuckles and Tails is Turbo Tails.
Obviously Turbo Tails isn't canon to the other verses, where his only transformation outside of the barrier form in Sonic Heroes, is Super Tails, using the Hyper Emeralds. Knuckles on the other hand, is just as capable with the emeralds as Sonic is, having a Super and Hyper form of his own.
On a side note, Comic Hyper Knuckles is pink, and this has lead to Sonic teasing him about it, even when Knuckles was turned into an evil god called Enerjack.
EDIT: And yes, I am sure Knuckles can go both super and hyper, look it up, its Tails who's the one with the handicap. Plus, if you really wanted to argue things, no-one knows if Shadow, Silver or Blaze can go hyper because they've appeared in all of one game.
