Can you spray copper fungicide while fruit is on the tree ?

Not a good idea. If your fruit has problems then it is already too late to do anything this year. But you can spray in late autumn that will prevent fungus living overwinter, and again in the spring BEFORE bud break.
Many fungus diseases overwinter on the soil then get splashed onto the leaves from heavy rain. You can prevent this by raking up all leaves, removing the top layer of soil in the autumn and adding fresh compost and mulch instead. Then spray the tree.
Copper fungicide tends to build up in the soil so don't do it yearly, but a few applications is ok. This is mainly why they stopped using it, but TBH what they replaced it with is systemic and probably more toxic to health than the copper.

The purpose which is? What disease on what fruit tree? Read the label. It can be used. But the problem is if your fruit tree has a disease, it is a recurring problem caused by having the wrong type or variety of fruit tree for your area. It will continue to happen time and again until you run out of fungicide or get tired of spraying. Then the tree will be overcome with the disease and die over the course of a couple of years. The best thing to do is start over and not have the problem. Plant what grows in your area and stop experimenting. You are not Johnny Appleseed who will discover a magical tree. Advice from a person who is a tree expert because he has killed so many trees in so many ways.
