since your zone name is 0.10.in-addr.arpa, the last two lines should be

254.207 	IN	PTR	guest.uah.edu.
16.204		IN	PTR	gateway.uah.edu.

then the fqdn will be 254.207.0.10.in-addr.arpa which is reverse for 
10.0.207.254

also the forward zone in named.conf should be only uah.edu

zone "uah.edu" {
         type master;
         file "guest.hosts";
};

since guest and gateway seems to me to be hosts in uah.edu domain, 
correct ? It is not clear to me from your setup.
