He sent me a screenshot where there is a delete button in the simple upload object.
On mine there is none although I am on 453

have you got the elements 'show media in form' option checked?

On his example it shows a thumbnail but in my scenario the uploads with be pdf files.
will the name of the pdf file be displayed on the edit screen so that the user can see if/what is there?

If you have 'show media in form' checked then yes, a link to the file will be shown in the form view.
