I used MediaInfo to get info about some audios. It shows 1 channel for some and 2 channels for others. Does it mean that sounds with 1 channel are mono and those with two channels are stereo ?

Note that "mono" and "stereo" are short for monophonic and stereophonic. –  sawdust Oct 25 '12 at 18:57

Yes, channel in audio is a stream of information.

An audio device supports one or more channels depending on configuration. Mono audio has one channel, stereo two channels, and 5.1 surround has six channels.

Yes. Generally 1 channel audio can still be played through a stereo headset or speakers, it is just the same signal going to both instead of a signal going to each side.
