Answer 1

There is such a program, according to your description, control for the Computer Club, though off. You can download a trial version of the site, I didn’t look deeper, I think it’s just right for you. https://astrumsoft.com/download/
The program consists of two parts, server and client. The server part is installed on the administrator's computer. This is his workplace. The client part is installed on each computer in the local network.
Computers are blocked using several mechanisms: an unclosed splash window and keyboard / mouse blocking.
The program can remind the client how much time he has left (or how much he has used), including by voice, 5 minutes before the end of the time, directly into the headphones or through the speakers of the administrator's computer.
