CIDR IP address question

Are the following IP address ranges in minimal format?
These are listed in our firewall, but it seems like we could do with fewer lines?
(i.e., is there overlap/redundancy?)

 80.255.51.0/28  
 80.255.51.16/29  
 80.255.51.64/29
 80.255.51.88/29  
 80.255.51.96/27  
 80.255.51.136/29
 80.255.51.144/29  
 80.255.51.200/29    
 80.255.51.208/29  
 80.255.51.216/31

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

According to this calculator http://www.ipaddressguide.com/cidr , you can't combine any of those to reduce the list.  Although a couple of the '29's look like it, if I change them to '28's, it changes the starting address.
