@Seuli Das Majumder Welcome to the Microsoft Q&A platform.

Is azure data lake analytics account only support data lake storage Gen1?

Yes, Azure Data Lake Analytics supports only ADLS Gen1.

Note: We do not have plans to support ADLA-ADLS Gen2.

ADLA does not work with ADLS Gen2. We recommend that customers use Azure Databricks or Azure HDInsight instead of ADLA when working with ADLS Gen2.

Data analytics account locations are very limited. if storage account is in different location than analytics account, will that able to access data from storage?

Azure Data Lake Analytics available in regions of East US 2, Central US, North Europe, and West Europe.

Note: Azure Data Lake Analytics and ADLS Gen1 accounts should be same region.

Example: If you deployed ADLA in Central US and the ADLS Gen1 should be in Central US.

what are the differences between these different storage tye like Gen1, Gen2 and blob storage?

Azure Blob Storage is a general purpose, scalable object store that is designed for a wide variety of storage scenarios.

Azure Data Lake Storage Gen1 is a hyper-scale repository that is optimized for big data analytics workloads.

The table in this article summarizes the differences between Azure Data Lake Storage Gen1 and Azure Blob Storage along some key aspects of big data processing.

Azure Data Lake Storage Gen2 is a set of capabilities dedicated to big data analytics, built on Azure Blob storage. Data Lake Storage Gen2 is the result of converging the capabilities of our two existing storage services, Azure Blob storage and Azure Data Lake Storage Gen1. Features from Azure Data Lake Storage Gen1, such as file system semantics, directory, and file level security and scale are combined with low-cost, tiered storage, high availability/disaster recovery capabilities from Azure Blob storage.
