Since a group of photons is constituted of individual photons,
diminishment if the group applies to the individuals if sanity means
anything in physics.

Incoherent.

The inverse square law applies to a group of photons and says the power
density, that is the power over an area, decreases with distance. This is
because photons can not be perfectly collimated and thus have a
dispersion angle. From this, high school geometry leads to the inverse
square law.
