I'm assuming you're talking about IPv4. It would be possible if the DHCP
client(s) provided three different client-ids. (client-ids are used in
preference to MAC addresses to identify clients in DHCP). Your main
problem would be finding a client which will support that and cope with
multiple addresses, I don't know of one that does.

See --dhcp-hostsfile. Put the host declarations in a file, tell dnsmasq
about it and it will be read on SIGHUP.
