How to do serial circular cuts like this (see in the description)?

[Micho6]

I want to do circular cuts (holes) in ribs of an aircraft:

I want it to look like this:

The problem is each rib is different, therefore there is different number of holes in each rib, different diameter size of each hole, and different distance between holes centers. Doing cuts for a single hole separately is possible, but it takes ages. Is it any way to do it automaticly/serially? Thanks in advance (ribs file in the attachment)
