Welcome to the forums!
I would recommend training the puppies seperately when teaching something new. For example if neither puppies know sit, you can either have them both on a leash and work with them simultaneously with one person for each puppy. or seperate them by crating one and working with the other in another area. Once they both know the command then you can work with them together. When you work with them both at the same time make sure you are using highly motivational treats so that the dogs will be most interested in you.
Working each dog seperately (whether with two people or seperate sessions for each dog) helps them to build a relationship with you. When two puppies are raised together, they can have a tendency to bond more closely with one another than with the owner. They also tend to distract each other easily.
Keep us posted on your progress!
