These URL getting clicks and impressions and also ranking but my major concern is Server Error (5xx). Lot of these URLs are coming to server error

So I removed them and added no index tag. Now what should I do to remove them quickly and permanently from index. (1/3)

So is it good idea to remove them using URL removal tool. I want to know google woule be able to know the noindex status. Because previously I added them to robots.txt and blocked, then I realised google would not be able to read noindex tag. (1/2)

But our all content we upload to our website either image or video, so do we need this to be implemented

It's applicable to cloud hosting only or any other hosting, like hostinger or bluehost.

Hey @johnmu.com it can't be a reporting issue as the same thing is happening in analytics & even in Google AdSense.
