It is indeed impossible to place more than one hyperlink inside a single cell.
A workaround to make it *look* like more than one hyperlink exists in a cell is to place (in your case) 5 separate transparent activeX label controls onto a cell, each with their respective caption, and each whose Click event will take you to the destination that the respective hyperlink would have. You can also manipulate the label's properties to make the text color blue, and underlined, so it will look to some people like 5 hyperlinks actually exist in the cell, though really they are none but all on transparent activex labels embedded in the cell.
