How i can get tags and values in firebase and make compare?

I mean the structure of database is correct ?
And when i login in user i get all data for this user by put project bucket as global variable
But how if i want in same screen fetch all data for other users ?

Yes - it will work
Yes - if you use the blocks I showed for a user
Use the blocks I showed for all users

We had a very nice school bus tutorial in the Firebase FAQ, but it was monetized to death.

I would put them all back under a topline tag called Users. This will make it easier to access just this data, and reduce confusion with any other topline tags with different content that you may wish to add.

Did you mean same first structure ?
Use projectbucket as users then put inside it user

This should give you an idea of what you can do:

Firebase data:





This is a different question....

Assuming the student is signed in to the app, and they are on the bus, they should be getting their latest position. Their app should then be updating their firebase data with their latest position (LocationChanged event)
