Way too many nest boxes. In a 4x8 coop you can only have about 8 birds. Usually you need only 2 nest boxes for 8 birds. You need to provide roosts for sleeping, as you wouldn't want the hens to use the nest boxes to sleep in. They are for laying eggs, and nothing else. Therefore you would need to have your roosts higher than the highest nest.
Just a couple of observations. Good luck!
