you can throttle the bandwidth per IP address with the traffic shaper. DHCP
will have to be setup to assign fixed IP addresses to the MAC addresses of
the clients, denying access to unknown MAC addresses. Note that it's
possible to spoof MAC addresses with some NICs.

Anoterh way would be to utilize the captive portal, together with a Radius
server. Without the Radius server, the captive portal can throttle the
bandwidth only. The captive postal can send accouting packets to the Radius
server, which can log the generated traffic per client and, if excess
traffic is detected, deny client autorization the next time it tries to
(re-)authenticate (the captive portal can be configured to reauthenticate
periodically).
