Hi GeneDaniels,
Do you want to propagate the tree ?
If yes, then keep some additional shoots and airlayer them as soon as they are three inches of height.
If no, then they are just "garbage" and as such you should take them out as soon as you spot them.
Those shoots being the closer to the roots they will drain a lot of energy for nothing.
For the five shoots you are keeping, try spreading them so that they don't shade each other. That will help grow quicker and as always, fertilizer, fertilizer ... and proper watering .
Today here it is raining, so my watering tasks are already completed :).
