The installation and configuration was successful. BUT when I try open Home (http://127.0.0.1:8080/apex) return error 404.
This config was in port 8080

You can have a look at other web applications in /webapps to see how correctly structured look like.
You can also read this (very old) but still informative post.
From what you say, it seems you have several challenges:
* web-inf is in lower case instead of uppercase
* the web application is named "uk" and not "demo-examples"
Have you tried with http://localhost:1020/uk/HelloWorld ?
