How do I work it so a board member does NOT get re-elected?

There are probably some legal guidelines, not just "rules" which must be followed.You need an attorney. This little five person group represents a larger group of people and by law (at least in California), but follow approved accounting methods and be audited by someone outside of the group. It sounds like you've got a big mess on your hands and that there has been a total breakdown of the system. If legally this turns out to be something like a board of directors in a corporation, you could all be held liable under certain situations. See the lawyer.
