Depends on if any and how early any stamens/bananas opened and/or they released any pollen.
If you found the stamens/hermie early enough, there should be no problems for your other pants.
If they opened 2-3 weeks ago, unfortunately you might find seeds in the other plants.
Remember too, if you do find seeds, the seeds will be hermies, so not good for anything. Unless you want to grow hermies of course!
Hope this helps,..........
