Look at my chkpass type in contrib. There is a function to verify the
password. It is just a placeholder now but you can modify it to do all
your checking.
Policies 4 & 5 may require further work either in the chkpass type or
with a separate field. Details are hard to suggest as I can think of
three or four methods right away but it all depends on more detailed
requirements to determine the best one.
Non-database related suggestion: Reconsider 4 & 5 anyway. Forcing
people to change their passwords all the time is less secure, not
more. In those situations you tend to find a lot more passwords on
post-it notes and in clear text files.
