The hostname is in the dnsmasq.leases file.  Exact directory depends on how
you installed dnsmasq.  If you're using the leasefile-ro option, then
getting this information is dependent on your script saving it somewhere.
 If the client doesn't send a hostname, the hostname column will have "*" or
the mac address.
