I am not sure if the Tengu is Aya or Hatate.
She has short hair like Aya, but she has a tie and holds a phone like Hatate, however, does not have pigtails.
it may be an alternative hairstyle, but I'm not sure.

I'm fairly sure this piece is supposed to be a bunch of male or at least more masculine depictions of various touhou characters, considering the shorter hairstyles (mostly) across the board and the way the faces are drawn, and a quick machine translation of the commentary seems to agree with me, for what that's worth. With that as well as the phone that they're holding in mind, I'm pretty confident it's Hatate.

"東方男体化" would be "Masculinized Touhou" or "Male-form Touhou" so you're right on the money there.
