yes I could listen to them all, they were different stock game sounds.

I couldn't listen to them until they were extracted, at which time it seems they also became waves.

I could replace the original and name the new one the same, but I don't know How to change the format of this new wave to the format those files were, unextracted.

With the files that have proper names it's dead easy.

Imagine the file you extracted is called xxxx_00.wav, you just need to change the new sound file's name to xxxx_00.wav and then copy it to your files/samples directory. Then you need to add that path and filename to your filelist.txt file in the root IL2 directory. And that's it.
