I felt like

Rokyou-san: Yamazaki-kun (not because of lies but because Yamazaki-kun seems so chill and unperturbed)

Makiu-san: Chiharu-chan, as she is very energetic & keeps Yamazaki-kun from annoying people or fooling people 😅

But of course, it's possible that Makiu-san is also like Yamazaki-kun and Rokyou-san is like Syaoron-san
