Sound Forge is a multi-channel editing application and is really not designed for multi-track recording and mixing. ProTools, Samplitude, Reaper and the free Audacty are multi-track DAW options. Vegas Pro video also has a substantial multi-track DAW built in, which Sound Forge can be integrated to.

That said, in Sound Forge and assuming your have a broadcast wave (poly) file, mute the unwanted channels, so any residual noise, is removed and 'Save as' an 8 channel PCM <.wav> file.
Alternately, you could copy the desired channel's waveforms and paste them the channels of a new 8-channel file.

You can also extract interleaved tracks from a poly file (as multiple mono files) using Sound Devices' (free) Wave Agent and import the desired tracks into your preferred multi-track DAW.
