Multiple Hotspot at one interface

HI, I installed RouterOS on a PC and I have two Interfaces one for LAN and another for WAN, I want to Run Multiple Hotspot on LAN interface How should I do that? I wanted to add 3 level privileges to our employees, and I wanted to do that through hotspots. if you suggest another way to add 3 level privileges you are welcome. (my mean of 3 level privileges are: some of user can access youtube and social medias some of them just can access email and google)
