Let me try the Alan advice for this issue and I will update the board.

Thanks Devin your detailed answer, it will help me to handle other low quality pages.

We have some pages targeting the different countries but with the Near to Similar content/products, just distinguished with the country name etc.

one of the page was assigned to me for optimizing. two or three Similar pages are ranked with in top 50 for the main keyword. I updated some on page content to make it more distinguish from others. After some link building, I found that this page still not showing in Google result, even I found the following message on the google.

"In order to show you the most relevant results, we have omitted some entries very similar to the 698 already displayed.
If you like, you can repeat the search with the omitted results included."

I clicked to repeat omitted result and found that my targeted url on 450th place in google (before link building this was not)

My questions are

Is google consider this page low quality or duplicate content?

Is there any role of internal linking to give importance a page on other (when they are near to similar)?

Like these pages can hurt the whole site rankings?

How to handle this issue?
