Cherry laurel are susceptible to infection by fungus or bacteria. To find out the exact agent of infection you need to collect fresh samples where the leaf spots are starting and take them to your local Penn State Extension. The extension will send the samples to the Penn State diagnostic lab and you will get a report telling you the problem and the solution.

Am including three picture of the cherry laurel that has the yellowing leaves with the yellow dots and dark round centers, the yellow leaves eventually fall off. I am collecting them and keeping those leaves in a zip lock bag. I did buy a fungicide spray that contains cooper.

Did you get the three pictures of the cherry laurel that I  just sent ?

The holes and brown spots look like a fungus or bacteria at work. The yellowing on the leaves can be environmental meaning the plant is too wet or has a nutritional deficiency. It's important to identify exactly the cause of the problems so you can get the right remedy. You can check the soil to make sure the roots aren't in an area that is too wet. You can examine the leaves for insect activity as well as the dark spots which seem to be fungal. Your best bet is to get the leaves tested by Penn State so you know for sure what is wrong. Many signs are the same for different causes, so it's hard to tell without a test.
