It’s great that both mothers can share the raising of their kittens together. It gives them the support they need to care for their kittens. One thing that you need to do is to make sure that all kittens are getting fed, from both litters. The bigger kittens will crowd out the smaller weaker ones, and then they will become sick and die. If this should happen, you can supplement them if need be with formula or goat’s milk. Once your mom cats get their kittens weaned, you will have to spay them or they will end up having more kittens–which unfortunately in my experience they rarely raise because they are exhausted from two pregnancies and nursing kittens. The first two litters will need spayed and neutered too.
Hopefully there is an animal welfare league close that can help with the cost of spaying and neutering.
