Hello Alexandros,
The only reason a URL would not be indexed because of Rank math is if it is set to noindex. Other reasons can be exclusion from sitemap either manually or by adding a canonical URL in which case a page interpreted as duplicate.
In your case, the post URLs don’t seem to have an issue.Sometimes new sites and posts take some time to appear on Google. Please note that indexing by Google depends on a lot of factors. Your posting frequency + the domain authority are just two of the many factors Google considers when indexing some new URL. Google assigns a crawl budget to your website depending on these factors (especially these two) and that has a direct effect on how soon or how late your content can get indexed. It is likely the news site you are linking to has more domain authority which is boosting the new site to be indexed
With that said, we have found that barring any issues like copied/DMCA/low-quality content issues – Google usually indexes posts within a week or two. So, we request you to kindly wait.
Google even says that on their official website:

The above screenshot was taken from this page:

So, you have to be a bit patient and allow it some time. If your website isn’t indexed even after a week, you can place a manual indexing request here:

Finally, it all boils down to the quality of the content, and if your content improves Google’s overall search index.
Please check this article where one of the Google employees mentioned:
“If your site relies on manual index submission for normal content, you need to significantly improve your site. Search console does not fix your site, you need to do that yourself.” – JohnMu

With that said, here’s a good article on how to ensure that your website gets indexed regularly:

With that said, send us the URL of the page that is not indexed so we can check if the reason it is not getting index is a setup issue or if it is just Google taking its sweet time to index your pages.
We look forward to helping you.
