It depends on what level of education the student is at. College yes, high school and middle school no.
Bad effects on carrying your mobile phone to school is it could get stolen, broken, you could get suspended, or detentions. Your parents wouldn't be to happy about that i know from experience.
Balance should be
yes but head
No, students should not be paid for attending school.
No. School is for learning and to learn requires a student to listen. If a student has music he/she is not listening to instructions or how to do something.
You should immediately send the student to the school nurse.

Yes it is really important
4 mintues should be enough to do everything for a high school student.
yes there should be and there is. school gives each student a student number/pen number(if you're in high school) so that only that student can see his/her grades. also, lockers protect individuals' privacy.
Middle school student should be able to go to there locker a certain amount of times during the day. This is so that the student does not have to carry all their books around.
