What do you do? Build up excitement that you've got some nice multiple pups there and then when they're 2 feet tall min, decide if you want to separate them, chop them, or keep them. I prefer keeping them unless I want to sell or trade or give them away. Pups growing as a "mat" with their mother plant are perfectly fine and take up much less space than having them separately growing nearby. Plus with some varieties it's a bonus. For example, the "Double" banana only produces twice the bunches when the pups are still connected as second gen plants with their mother.

Edited to add, didn't notice the pot issue. I'd separate them in this case, but it doesn't hurt to wait a while before doing so. You want them big enough to take the transfer well.
