What should I do if same content ranked twice or more on Google?

[AccessTechBD]

I have a Bangla SEO related blog where I have written article like "Domain Selection" "SEO Tools" "MOZ" etc. All the article has been written in Bengali language.  I have used wp tag for every post. I have submit xml site map generated by Yoast SEO. However I kept  "no index" for category. I know well duplicate content is a major problem for SEO. After publishing my content Google ranked them on 1st page. But my fear is that most of the content twice or more. The keywords are ranked by post, wp post tag and Archive. Now I have a fear of penalty. Please check the screenshot and please suggest me what to do.

I would say the first thing to do is to send a thank you letter to Google   the more times you show up, the more traffic you will get.

If you have two pages with identical content showing Google will probably drop one in due course, you could consider restructuring one of the pages to go into the topic in more depth but you must keep it within context to avoid losing the ranking.
