Share GBs between the users in a company

Share GBs between the users in a company

I would like to ask you if it is possible to share the GBs between the users in our company. As you can see from the image all the users have 10GB Basic Storage (each of them). Some users only needs 1-2 GBs because they are not active users in our company. So is it possible to use the other 8GBs to another user (in the same company)?
