Bb soprano, C soprano, and Eb sopranino saxophones.
The Bb soprano is the most common of these- it has experienced an incredible comeback in both the jazz and classical genres; it is now widespread despite the fact it was almost extinct forty years ago.
The soprano in C has not been so lucky- it is now no longer made. It has a slightly reedier sound than the Bb soprano, but it is quite similar in tone.
The Eb sopranino has a very direct and pure sound, and is the highest pitched saxophone originally made by Adolph Sax. He had plans for one in F, but there is no evidence it was ever made.
