OP, these tracks have over 5 instruments... be more specific. Is the instrument playing the lead melody? When does it start playing?
Well I know in the two versions Charming Domination that for the Yukari version of the song (and for Necrofantasia) the primary ZUNpets were swapped out for harpsichords.
What you're hearing is a synth stack. A harpsichord sounds like
this. There's not a single harpsichord in either of those tracks.
So, the standard trumpet is much more different than the ZUNpets? If yes, then is it that rare? Because I want to buy one.
The ZUNpet is a set of samples (recordings) of a common trumpet being played with mariachi-style vibrato. These samples are resynthesized and played by a hardware synthesizer.
This video shows the difference between "normal" trumpet vibrato and mariachi-style vibrato:

And, does Youkai Mountain ~ Mysterious Mountain uses a flute or blowing musical instrument?
It's bottle blowing.
