How to introduce new puppies to 3 mean dogs?

[i am me <3]

I have three socially retarded dogs and they aren't very nice but i just brought 2 puppies(one will be moving out sometime in the near future) i introduced them through the crate and they seemed fine.
When i took them out and watched carefully with my family, one dog was pretty easy and didn't seem to mind, while my two other dogs, did.
One dog(sadie) is very cowardly around them both but she feels threatened and barks and jumps toward the puppy and as she does so, the other dog(jack) will dart toward the puppy and start attacking it then sadie will start attacking.
Although no one has been attacked yet, they have attacked my aunts dog and its not pretty!
So how do i properly reintroduce them?
my dogs are fine...and animal control will not take my pups away, because we watch them and i know a pup wasn't a good idea but it wasn't my idea. Plus im not looking for opinions, im looking for ANSWERS for my pups best interest!!!
