Must and have to (Obligation)

You must take this train if you don't want be late
You have to get up early because the train leaves at 7.00 am
You must help my brother
My niece had to do her homework yesterday because today she has no time
I have to go to the hospital to visit my neighbor
You must turn off your mobile phone in the hospital
I have to do my composition for next week
