Can somebody tell me which of these is secure and which are not.  I mean....probably none of them are secure, but just give me an idea of which are reasonably safe because of the relationships between the zone.  

If I were to ALLOW ALL SERVICES, ANY SOURCE TO ANY DESTINATION on these, which are reasonably ok?  If any are big security concerns, why?
