Any musicians there? Is there a word for musical instruments that can play only one melody simultaneously and those who can play several? Is it "polytonic"?

Like, wind instruments can play a single note by definition.

You can play two strings simultaneously on a violin, but it's usually a chord. I think you could change the pitch of only one string to make the melody more complex, but you can't play eights on one string and quarters on the other.

I have no idea if you can play two melodies on a guitar. Theoretically it should be possible, but I can't think of an example.

But a piano or a harp can do this.

Here's Metamorphosis II arranged for a harp. Here's the same composition arranged for a violin and a piano. Lavinija can play both the rhythm line (can I call it the baritone line?), the bass note and the main melodies on her harp, but Anne Akiko can only play the main melody, she shares the bass notes with Reiko Uchida on the piano and Reika has to play the baritone line.

Or, to invert the question, is there a word for music you can arrange for the piano and can't arrange for the flute? Even if that flute was so long it could play any note?

I think part of your problem is your terminology. No music has more than one 'melody' happening at the same time. There are 'countermelodies' which often support or contrast a melody (example, Bach fugues) but very few pieces truly have two melodies at the same time. in this clip Chales Ives has two groups of the orchestra play 'America' in two keys in two different rhythms, literally two melodies.

@KMC I think fills in your other question.

Or, to invert the question, is there a word for music you can arrange for the piano and can't arrange for the flute? Even if that flute was so long it could play any note?

Not really, as in as far as I'm aware there isn't a specific term. There are limitations to every instrument, and it's up to the arranger to arrange things in a way that makes sense for the instrument(s) the person is arranging from the original material.
