No result in Google search

I am using this plugin on my website Vidyasagar Academy, but there is no result at all in Google search pages.
I tried live google searching with keywords, tags for my hreviewed posts and all that, but no google search result at all.

I have paid Google CSE, so I indexed all hreviewed post links on my website, in CSE, but those particular post entries are vanished from Google live search pages.

I tried hiding and displaying the hreview box, but nothing happened.(Is it so that there is no google search result, if I hide the box?).

Then I tried to put the entire title of my hreviewed posts in Google live search but no result.

Please help.

The links of my hreviewed posts are as follows:

• https://vsagar.org/latecomer-student/
• https://vsagar.org/free-environmental-science-projects-for-12th-standard-students/
• https://vsagar.org/open-book-test-chapter-1-instruments/
