Every application are by default multi user (if you don't have any security). You no need to do anything for it.
If you want to test it on local environment then your computers should be in same network and using IP address you can access on another computer.
Just run your application on 1 computer and then access it on another computer. You will be able to login on every computer with same login.

Answer 2

for bigger project there is server software like Tomcat and framework like Spring boot that has all features and tools what you need. Then your code is running on server in container and communicate with other computers via some protocol or service
