Four never opened inserts for your Filofax, all made in the 1980s and one a little more recently.  These appear to be unopened packages so contain whatever was typically included.  This grouping includes 1 Telephone Calls Planner, 1 Telephone Numbers, 1 North American Area Codes (from the 80s, so definitely missing a few new area codes!), and 1 Most Used Telephone Numbers list.  Most if not all of these are no longer made.
