100mbps fibre internet, 40+ computer , how to set limit

im currently operating a internet cyber cafe running 100mbps fibre internet connection , having around 40+ computer on and off , how can i set a limit per computer that can be automaticly adjust between computer?
mostly running on online games , youtube , online streaming
how much bandwidth i should set per ip ? or theres automatic distribution available in this microtik?
if not all computer is running can other computer share the bandwidth

simple que with burst connection burst and also limit bandwidth is good?

i have search all the method on the forum and theres too many of them i tried some of them but its not working really good.

ip range 10.0.9.0-255
using microtik routerboard 750gl
fibre inter is dynamic ip ,
local ip is static ip.

im not sure if i said it correctly because im not a computer guy.
