What is the source for the suggestions page in the tool?

I believe they are coming from the various Content translation/Machine Translation engines, depending upon which language pair someone is going between.

Yes. But, is there any particular page which displays the list of articles that are displayed in the suggestions page?

Oh! Sorry, I misunderstood the question. For that, see Content translation/Documentation/FAQ#What are the "Suggestions" in the dashboard?
