3:1 is the minimum for caged birds. 5:1 is better. Larger quantities per male will still result in good fertility. It's really up to you. I've had 2:1 (with only one male--this would not work with multiple males) for a long time in an aviary where the females have multiple shelters and hide-outs across 100 sq ft, so they can easily escape the male's advances. In smaller spaces, the ratio must be higher to prevent baldness and stress. I prefer a higher ratio even in large spaces--but I made the mistake of trying to save on feed costs by not overwintering, and now I can't find a source to replenish my stock, so I'm stuck with what I've got for now.
The reason you see such variability in suggested ratios is that everyone's situation is different. It depends how much space they have, how many males, whether they are on the ground or up on wire, whether they have multiple hiding stations, enrichment opportunities, etc. So most people start with a ratio that feels comfortable for them and adjust as needed.
