Well, isn't that a happy little question! To get folks to join your server in Gmod, you can start by creating a welcoming atmosphere with clear rules and helpful moderators. Encourage players to invite their friends, host fun events, and showcase the unique features of your server. Remember, just like painting, creating a positive community takes time and patience, but with a little love and care, your server will surely blossom into a happy place for everyone to enjoy.
It depends on what kind of server you are running. If it is a listen server (i.e. you started it from the main menu of the program) you might want to grab your dynamic IP address which you can get from www.whatismyip.com, then tell your friends to open the developer console (They have to have the option checked under Options > Keyboard > Advanced Settings > Enable developer console) and type "connect (the IP address you got):27015" so if my dynamic IP address was 10.170.19.90 I would type "connect 10.170.19.90:27015"
(without the quotes though, be mindful of that). Once your friends enter that they will be on their way.
As for a dedicated server (i.e. one run with a Dedicated Server tool and technically isn't Gmod but just the server itself) you can invite your friends by way of the Steam In-Game Interface.
First of all you need to go onto gmod, then when the main menu has loaded up you should see a multiplayer part, click on it and a menu will open listing loads of server, decide which one you want to join, then double click or click join then wait for the files on the server to be downloaded then your done.

It depends how the server is set up. The owner of the server can change the size of the server to let more or less people join.
First off, an online server means that the server is up and running. It is available for people to join. An offline server means that the server is down and closed for people who want to join.
