Answer 1

You first need to study this - https://ru.wikipedia.org/wiki/DNS
Then this - https://ru.wikipedia.org/wiki/%D0%92%D0%B5%D0%B1-%. ..
After that, you need to поддомен.сайт.руturn, for example, through CNAME, to сайт.ру, and make settings in the web server сайт.руso that everything works. Instead of CNAME, you can use an A record, where it looks at the same IP сайт.ру. And the web server settings depend on the software that is used - Apache, Nginx, etc.
