A stereo sound is a sound consisting of a left and a right channel. Praat can read and write both mono and stereo sounds.
If you read a Sound into Praat from disk with Read from file..., and that sound file is a stereo file, the resulting Sound object will be a stereo Sound.
If you want to look at the left or right channel separately, you can use Extract one channel....
If you choose Save as WAV file..., and the sound is a stereo sound, then the sound file will be a stereo file. If you have two mono sounds and you want to combine them into one stereo sound, you can use Combine to stereo.
