Without knowing what queries you're using for each of the five documents, I can't really advise on the specifics of how you'd combine all five documents - I can only give general advise such as in my last post. The DATABASE field can certainly be used for your multi-record table. For what you're doing, a Directory merge would probably over-complicate things. For a non-mailmerge DATABASE field implementation, see:
