@arunpatidar , @lukasz-m , @Jörg_Hoh , @SantoshSai    Am I missing anything here? Please correct me.

I have replicated the process [reindex the custom index , delete the custom index and reinstall the custom index again] on my local AEM 6.5.12 instance and every time it's picking custom index over  /oak:index/damAssetLucene.   Could you please reindex your custom index again and check whether you a...

In our project also we are following below folder structure to organize the components -   /apps/<project/site>/components/structure —> project or site specific page components goes here/apps/<project/site>/components/content –> project or site specific custom authorable components goes here

But you have to think about activation separately. Option2> You can write a groovy script to access those f...

Bulk editor is available on AEM as a cloud service also. But I haven't use it on AEM as a cloud service personally.   I have used bulk editor on different AEM 6.5.X.
