Great questions! This is all about the art of arrangement. And in this case arranging for a recording.

It's always best to experiment & see for yourself what works & what doesn't. In my experience, I've read that certain guitars, chords, harmonies, etc. will typically work in certain ways, with or against each other. But until I actually tried it myself I didn't know why or realize what my own particular tastes were.

After doing a lot of that kind of arranging & recording I have a much better idea of what works, why & how.

To answer your questions.

The other guitar should play something that compliments the first part. It should work with it & not against it. If it interferes, it will sound cluttered & bad. This part could be the exact same thing, which will typically make the whole thing sound louder & more powerful. But if both parts aren't played pretty closely in sync, then it will probably be a muddy disaster! :)

On the other hand they could be complimentary parts that completely stay out of each others way. But that still means they are playing the same thing musically.

A nylon string acoustic could play open chord voicings low on the neck while an electric with a clean tone can play the same chords, but different voicings of them up higher on the neck.

So, using different guitars, chord voicings, timbres, playing busy on one guitar & sparsely on another, these are all options to try when arranging for multiple guitars in a recording!

Anders explores some of these options with examples in the Rock course.

Also study some of your favorite songs to see how multiple guitars are arranged. For example, this Beatles song uses multiple guitars in clever ways.
