Adjusting multiply layers in PS

[Pumbas]

Hi everyone.
Lets say i have cardboard box diffuse, which i made from photos taken by myself:


i made photos with slighlt diffrent ligting -> the sides dosent match.

i know i can fix that just by using hue/saturation filter, but its kinda common situation, so i dont want to waste time on each part separetly.

how can adjust few layers at once?

solution i can think of is merging few layers, desaturating them and then masking on this colour i want.
but my goal is to make these layers just same hue/sat/brightness as fast as possible .

ps. it may be basics etc, but i would appreciate some useful trick

Well I would try using a levels adjustment layer, that could work.

Otherwise I would just use an adjustment layer for each side (use masks) and try to match the lighting.

Not much else you can do.
