Hello Muluken Kindachew,
Thank you for posting this in the Microsoft Q&A Community.
From my understanding, you would like to know how to view the members of a group in your Entra ID tenant.
To do this, log in to the Entra ID tenant with at least an account with a Directory Reader role. Search for the group then click on the member blade on this group.
Follow the link to see the steps on how to manage an Entra ID Group.

Once you are in the member blade, click on the Bulk operation and then download the members
You can also extract this via PowerShell by running the Get-AzureADGroupMember command. Follow this link to get more information about this.
Let me know if further assistance is needed.
