All you have to do is to host a server. Go on YouTube to find out how to host a server and then you have to port forward it. It takes a long time but it will be worth it because you can play with your friends more and now have to face creepers alone.
You need be on the same internet and there name will appear with the list of worlds then click to go on their world
You have to create a server and load the map to the server.
Of course you can. Minecraft has a folder with worlds in it in Application Support, so just put the map in.
Yes, it is only a custom map. All custom maps are free, and you should never have to pay to play one.
You can make a custom map on minecraft with out a map editor by building or demolishing certain land features or you can use a seed by typing your seed in the bottom box on the "create new world" menu.
No it is a custom built map
Put the new map in the minecraft_server folder then open the server.properties file and add the name or number of the map next to level-name=.
