List of all licenses and their meaning and function?

Hey Folk,

I need help because I don't know exactly which license is actually responsible for what due to the large number of licenses. I would like to assign the necessary licenses to a group as precisely as possible and remove those that are not required. To do this, however, I need to know exactly which services are behind it, here is a list attached via screenshot. In my specific case, it's about intune managed devices whose users mainly use office, exchange, onedrive, sharepoint and teams.

Does microsoft have a list of these anywhere? 

Thank you!
