This move by Indian Government is welcomed across the entire country since China has also blocked Indian Newspapers and Websites. These Indian websites are even not accessible through VPN, since China has implemented technologically advanced firewall.
When and how this ban is going to be effective is yet to be determined. But we can assume that these apps will slowly disappear from Play Store or Apple Store for users in India. Those who currently have these apps in their mobile phones will continue to work. But those apps which require active internet connection such as TikTok, UC Browser etc. are going to stop working while apps such as Cam Scanner will continue to work since such apps work offline.
However if ban exists and Indian users somehow continue to use these banned apps, they are not going to receive app updates leaving those smartphones widely vulnerable to cyber attacks.
Meanwhile Indian users can find other alternatives for these apps as there are a lot of them in app stores.
