Greetings Fellow Webmaster!

I must apologize for the mono toned robot fashion sounding question I am only allocated 150 characters to ask my question and the question would not have made sense with out at least a small bit of example info tied to the question. Did the best I could. Below I will explain further in much better detail. For simplicity consider all of the following domains and details to be examples.

I have a website that sells a product. My sites primary domain name is as follows.

Primary Domain: mainsite.com

I purchased 4 domains for branding reasons, copyright reasons, infringement, etc. They give me zero SEO benefit however I want to avoid any SEO penalty. There are two parts to this question. Rather two things I want to do and not do. Not getting penalized by Google is the first.

Purchased Domain 1: domain1.com Purchased Domain 2: domain2.com Purchased Domain 3: domain3.com Purchased Domain 4: domain4.com

All the redirects are set up properly. Best of my knowledge anyway. All 301 permanent redirects. As you can see here in this image. Each domain is set up the same.

After performing the following Google |Dork| (site:www.domain1.com, site:domain1.com) for each of my sites all looked fine. By fine I mean that none of my sites were indexed in Google. Each of the four sites properly redirected to my main domain via a 301 and none of them showed up in the index but one. ONE of the four sites shows in the Googles index. It has the same Exact snippet (meta Description, meta name, title, Etc.) as my main domain. Essentially Google has indexed it as my main domain. I have no idea why the others were not indexed and this one was, or why this one was and the others were not. I also have no idea if this is going to impact my SEO but my guess is it will and already has as I've not got the rank I thought I should have got as a fresh domain. It's not a big problem tho. Now that you have the background of the existing issue/problem now I can ask you my question and you understand it.

Question(s) - (1)Do I need to worry about this other domain being indexed with the same information as my primary domain. In terms of SEO will it effect me? NONE of the other domains have a site. They are just a domain with a .htaccess file redirecting them via 301. For now my main website is a singe page site. It has in it's meta tags in the head a rel=canonical tag saying the URL its currently on is the proper one. So basically the page is pointing to its self. (not sure if this work but I know it wont hurt.) (2)Should I deindex the other page via the Google Search Console? If so this is quite easy and will take only a few minutes to do so. I've not had this issue before on any site I've ever hosted so I don't know what to do about it If anything needs to be done in the first place. And lastly, (3)Have I left anything out that you can think of that I should know

Again, thank you to everyone who reads this and even more to those who respond. As always, I am grateful for your help! It saves me = )

(Definition for |*| - Google Dorks are commands built into Googles SERSI (Search Engine Results Search Interface AKA the Search Engine Command Interpreter. Or simply just "The Interpreter".) That allows for more precise searches and/or mass manipulation of data and text You've probably done some with out even knowing.)
