Is the model YHM-9360K the correct front sight to use with the model Arms #40 rear sight for the ORC? Will these iron sights co-witness with most holo sights or is the co-witness feature limited to a few holo sights?

For use with the ARMS # 40 rear sight a taller sight post should be installed in the YHM-9360K front sight. If you use any of the BMAS rear sights the taller sight post is not needed.
