We viewed your photos. The shrub in the left and right photo looks like it was subject to some minor chewing damage by an insect and cherry shot hole, a fungal disease.
Cherry shot hole is a foliar fungal disease favored by wet weather. The infected leaf tissue falls out and the holes are left behind. The damage is cosmetic and no chemical controls are recommended. Rake up any fallen foliage. The plant will recover.
The plant can tolerate some minor insect feeding and no controls are recommended.

Middle photo - This looks like a type of root issue. Perhaps planting too deep, excessive mulch, too much moisture, etc. We recommend that you replace the shrub. Take a look a our blog on cherry laurels and see tips for successfully establishing plants in your landscape
