Answer 1

you have two way : 1)you can install kerio control and add limited download for users for wifi and cable connection, or 2)you can download and install microtik router os and install that in your server and run hot spot and add users in that and run queue to restrict the internet access, way 1 is better and useful ,in kerio you can set login page for access internet for users
