google sheets – How do I do some data validation dropdown items can be selectable by only owner of the document?

I have a Google Sheets document which is shared with nearly thirty people and I added data validation dropdown to all the cells to not entering different values except I defined.

This data validation dropdown has nine items and I want to the fifth, sixth, seventh, eighth and nineth items can be selectable by only owner of the document. Can you please explain how I can do this?
