New technology user / editing question

Hi Forum, I have a basic start up question about Audacity. I have a stack of audios from miscellaneous court cases (ID’s removed of course). They remain in the FTR player.
I use Windows 10.
I would like to use Audacity to edit these files for classroom use. By that I mean I would like to delete parts of it and insert portions of explanatory narrative at various parts of the audio.

Can Audacity edit the audio on the FTR player in this way?

I look forward to hearing from you.
