I have plenty of flowers from 5 zucchini plants but only one lonely zucchini. Why are my plants producing only flowers? Thanks in advance for your attention.

The male blossoms typically drop from the plant and seemingly disappear. Give it some time and you will see it start fruiting.
If you continue getting flowers (including females) but no fruit, the issue is pollination. You may need to hand pollinate to make up for it. This article will help with hand pollination:
