How to find and select multiple values at once instead of one by one??

Hi. I have a spreadsheet with a massive amount of data. I've been given a list of values (i.e. U54x, PP32, h9A...) and search for the cells that contain them to change their style and format.
I can either look for each value individually and select its cell to replace its style or I can use some formula or some other mean to look for all the values at once and replace their style (same style for all cells)
I hope my question is clear. Thanks!

Here's an image to help you understand:

Use makeup data ... just a sampling ... say twenty or thirty samples.
