Windows (Bedrock) is the easiest client to setup. Once you've logged into your Microsoft (Mojang) account. Click on Play, Click Servers, Click Add Server and then put in the server settings below and save your settings. Click on the server to join the world.
Because the Medieval Faire is a Java sever, some Bedrock features (like custom skins, you will default to Alex) won't work in the world.
Phones and tablets are similarly easier because they allow you to add an external server. Go to the server tab, scroll to the bottom and click "add server" and put in the server settings below - you will see on the right that the server is up and running and you can join the world.
