Male to female ratio is often misleading, and/or focused too much upon. Age, breed, season, keeping conditions, and individual personality all matter in this case.
There is no perfect ratio that works all the time. If you free range all day, then you could get away with having more males. If your individual males are more mellow, they might not fuss too much with eachother, or the females. Younger males tend to be more hormonally driven, but it's not always the case.
If you're working with only one coop, and as such need your boys to not only be respectful with the hens and pullets, but also with eachother, it might work out for some time, but suddenly one of the boys decides he wants all the females for himself. You can't know for sure what will happen; if you do get a second male in your batch, then monitor both closely, and see if they stress out the females too much, or if they can't live together.
It would be a good idea to have a backup plan, maybe a small coop to place one of the males if things don't work out in the end
