You can bypass by either ip or mac here
/ip hotspot ip-binding
add mac-address=xx:xx:xx:xx:xx:xx type=bypassed
or
add address=xx.xx.xx.xx type=bypassed

You can set up an IP Binding for them with an action of bypass. I would also recommend setting up a "sticky" DHCP lease for them as well. This is because almost everything in the Mikrotik is handled by IP addresses and not MAC addresses, so if they get a different DHCP lease their bypass will no longer be valid.

i did the bypass and configured queue for each bypassed user using their ip addresses but the bandwidth is not effective on the bypassed users. what am i not doing right?

Just like in the firewall, order of rules is very important. Try moving them higher up on the list to see if that works. If it does, that means a rule before them is hitting them first.

You take the queue in the GUI and grab it and drag it to the top of the queue list. In the CLI you run "/queue simple move [queue ID] 0".
