WordPress AS a new web site with top-level domain – How to do it?

Hello.

Newbie seeks help! Thanks in advance.

I have bought my first paid hosting with DIRECTNIC (great pricing, by the way, you can buy one month, or 3 months at a time).

PART I

My intent is to have WordPress AS my site UNDER my new domain “https://www.christmasdreamthemes.com“

and also take advantage of my 5 gigs of hosting space to set up several other WordpPress sites (which I have done, I have 5 more in various stages of development that I have moved over to my new paid space).

I have probably done this all wrong from the start… because now, I can’t seem to find a correct and easy way (I think they use the word “compliant”, whatever that means) to put my first WordPress site directly under my domain https://www.christmasdreamthemes.com —

Here’s my WP url:

https://www.christmasdreamthemes.com/home/audentes/public_html/cdt-wp/

Could some kind soul please tell me, is there a seamless way to put this under my domain https://www.christmasdreamthemes.com ?

PART II

I have set up several WP sites in the same hosting space, and probably, I will use them all AS sites and disable commenting; although maybe I will allow comments in a part of one of them.

I would like to seamlessly & correctly integrate EACH of my WP urls directly under its own top-level domain.

For example, I want to integrate this WP site:

https://www.christmasdreamthemes.com/home/audentes/public_html/hcc-wp/

directly under https://www.habeascorpuscanada.com

If there is a correct, professional, SIMPLE way for me (NEWBIE) to do this, which also allows me to use the typical meta tags for title, description, etc., I will be grateful to know.

Thanks for your time.
