Hi Imran Nawaz, it is a pleasure to be able to help you.

Based on my knowledge, there is no specific order in which you need to shut down your farm (or bring it up).  All services will simply connect back up once the associated service is available.

And based on my understanding of the issue, the only rule I would recommend is to start the DC first, then the machine(s) running SQL Server, then everything else. Shutdown is the reverse. Since Stopping the cache results in partial data loss. The Feed Cache depends on the Distributed Cache service.

For more information, you can refer to the documentation: Manage the Distributed Cache service in SharePoint Server
