Hi @kumar kaushal - Apologies for delayed response!
You can check if the Hyper-V hosts can connect to Azure Storage using cbengine. All Hyper-V replication events are logged in the Admin log, located in Applications and Services Logs > Microsoft > Windows. Please refer to this document to know the event log locations. https://learn.microsoft.com/en-us/azure/site-recovery/hyper-v-azure-troubleshoot#event-log-locations
The following documents have the answers to all the other questions:
