How to apply no index tag to specific blog url without applying it to the entire blog slug?

Site URL: https://noahlangphotography.com/blog

I don't want to apply 

<meta name="robots" content="noindex">

to the entire blog page. I just want to target specific urls? Is there any way?

Thanks

The problem I'm having is trying to get old urls unindexed since the url slugs have been changed. I don't want the 404 responses on changed urls to be dragging down my websites rank. If there was a way to paste it into the head for a specific website, then I could target the old broken urls.

Rather than asking us a technical question about meta tags, it may help if you explain the symptoms you are experiencing so that we can help you to find a suitable solution.

Is it that visitors are arriving on your site using outdated links and receiving 404 errors, or is it something else. If you can include specific URLs, this will also help us.
