Ubuntu Server setup for multiple desktop instances

Ubuntu Virtual Private Server setup for multiple desktop instances. I want 5 people to be able to access the server simultaneously and access a personal 'Persona' (Profile) that will display in a unique (to them) virtual desktop.

Obviously security is important for the VPS.

A user will use AnyDesk to access the server and select their Chrome profile shortcut from the desktop. This will launch Chrome in a virtualised monitor for them to do their work (Ubuntu supports 7 desktops - Probably 3 people simultaneously as a maximum)

The users are friends, so the security requirement is from external hacking. The 'internal' security can be met with password protected folders on the desktop.

This is a fixed price contract and time for delivery is your choice. No extra money or time will be allowed - If you do not know how to do this, please, let's be professional and not waste each other's time.
