Hi my roommate have 2 10 week old Jack Russell Terriers Neneco (male) we got on June 27 and Nana (female) July 25. I have 3 cats before we moved in together. Neneco was very aggressive towards the cats we decided to get another Jack Russell for a playmate with Neneco we are also in the process of potty training the both of them and have closed off in an area of our living room and Neneco seems to overly playful (aggressive) towards Nana we put Neneco into a carring cage and back in the closed off area that seems to stop the aggressive playing but how do we stop the aggressive playing when Neneco is out of the cage with Nana. Neneco is very energinic and Nana is very laid back
Two puppies at once is not a good idea. You do not want a dog that already tends to be neurotic to bond to each other right off.
If you will keep them both then get separate crates and treat them as two separate dogs and not just "the puppies". Do separate training sessions and separate play times. Work with them individually with bite inhibition.
I know a couple jack rusell cal killers Start teaching them now thats not allowed. Some have such a high prey drive you will just always need to watch them. It definitely does not help to have two of them because they will feed off each other.

Most JRs I know don't get along with other animals much less small furry animals. They have an extremly high prey drive, and are very agressive players. A litter was born at the barn I used to ride at, and when those guys started playing, then sounded like they were killing each other.
sorry I don't have any advice for you, I have never owned a JR, and never really wanted one. I like small fuzzy animals also lol. Good luck
Honestly, you and/or your roomate need to do some serious soul searching and decide if it's right to keep one or both of these pups. JRT's are active athletic, have a high prey drive (as the others have pointed out), are very intellegent and can be dog aggressive. Are you willing/able to separate them from the cats or eachother, if the need arises? Are you able to provide them with enough exercise and activities to keep their minds busy as well. They are still young and have a good chance of finding great homes, if you decide you can't provide them with what they need. If you got them from a reputable breeder, they should be willing to take them back.
