I want to delete only one email contact address from the list in each
letter of the alphabet listing in Outlook. Please advise me how to
accomplish that!

Select the first contact with a left click. Select the next contact with
CTRL-left click to add it to the selection. Continue until you've selected
all the contacts you want to delete. Press Delete to delete the selection.
This is standard Windows stuff.
