Who composed Hineni? Who composed any of the tefilos? Some chazan

No, they're not. Most of the ones in the RH/YK machzor seem to be
medieval.

The few that made it into the printed machzorim became popular,
and once printing started people expected chazanim to stick to
the ones in the machzor so they stopped making up new ones.
