What ports to set for configuration files in laradock?

Question

Docker

Good afternoon.
By default, the default port for the project, which opens at localhost, is 80.
I created a few more projects, but they did not open in the browser, because nginx did not start, I found the answer in the logs.
Then I changed the ports to 84, 86, but still only localhost was opened.
Now, in order to run another project, I left only its configuration file with the .conf extension, for all others I set the .example extension.

I just don't understand which port to install so that all projects work, what is next to the laradock directory?

Why doesn't the installation documentation say anything about this?

Thanks in advance for your reply.
