When I import them to Vegas I don’t know how to map them or how to keep them loseless.
Set your project properties to 5.1. Each track should have a visual representation of the speakers, and you can pan the channel by dragging the orange dot (or however it’s represented in later versions) to the right speaker. Render as WAV/W64, and you won’t lose any quality owing to recompression.
Are that 6 mono files keeping the True HD?
There’s no quality loss upon converting to WAV.
I would like to obtain a single file because I’ve already edited a lot in the timeline and I could keep them if I replace the w64 5.1 file that I’ve using for the edit.
What’s incorrect about the w64 file? Use eac3to to produce one. As long as you set up each track properly, there shouldn’t be a problem.
