I had a lemon tree and it died and I cut it down. Left a stump from the trunk with green sprout growing from it. I have watered it until it is about 5' tall and real bushy and green. Will it ever produce lemons?

It has likely grown from the grafted stock on the citrus. There is no way to know the type of citrus stock used, an it could likely be a lemon stock that may not be very flavorful.
There is no way to know until is does produce if it is an edible fruit.
