as you can see from the picture, the drop down box doesnt have the basic property for the like of Job title so i cannot import this column from my excel sheet
What kind of import were you attempting? You're correct that Job Title is a standard property which should appear there, but that's only true of contact properties. If you were attempting, say, an account or deal import in-app - independent of what's on your import file - that might explain why it's not there.
If you had intended to import job title info on some object which is not a contact, you may need to create a custom property first, then import afterwards.
