With bananas, if you're in an area which is warm enough for them to have fruit, you'll get your best crop by having 3
plants per clump. One adult, which will bear the current years fruit, one half grown for next year and one sucker. All others should be removed or you'll get small dry fruit or no fruit at all. So, if you want fruit from the
tree, i'd suggest cut off all the suckers except one. Choose a strong sucker with pointed leaves, the rounded or fat leaved ones won't bear fruit. If you want to transplant the offcut suckers, then ensure you get some roots with it. A cut can be made with a sharp clean spade vertically and the sucker is then planted in the new area.
