Growing lemon trees. How long does it take for the tree to give fruit?

It may depend on whether or not the tree was seed grown or obtained from nursery stock. Oftentimes, lemons grown from seed may or may not produce fruit, but if it does produce fruit this may take many years, and when it does produce lemons, the lemons MOST LIKELY, will not be edible or extremely slow growing. Since there's really no way of knowing for certain, you could try adding more phosphorus (bone meal) to the soil to help encourage the flowering and fruit growth.
