I know in hotspots you can see how much bw each user is using. However is there a way to see the same type of info when the mikrotik is only acting as a dhcp server no hotspot enabled?

if there is only one device per port, you can just look at the data going across each individual port at any given time in the interface list

Unfortunately not they have several dummy switches through out the office.

Found it. Under tools do a tourch on the bridge and it will show you everyones bandwidth
