Hi Pawan,
In general, Azure is not licensed by user, but a central or shared subscription (or multiple subscriptions, but not tied to a specific user). So, in this case, you should have the subscription and then invite the users with the appropriate permission (role assignment in this case).
To create a subscription you have many options depending on your current licensing program, location and organization needs. You should talk with your current reseller to enable this product in your current educational agreement.
