mosja- Have you ever get caned by the teachers in an international school?

You need to use been.

mosja- Which class schedule is better international or our local school?

This is unfamiliar in the UK. Do you mean this https://dictionary.cambridge.org/dictionary/english/timetable ?

mosja- Does your international school have elevator?

Use elevators in AE or lifts in BE.

mosja- What is the finish time in an international schools?

You should use finishing instead. While this is possible, asking what time a school finishes is more likely in the UK.

mosja- Does indoctrination occur in the international schools?

This is written well enough but, the meaning in context is unclear. What does the yellow part mean?

mosja- What life is like in an international school?

One word is in the wrong position. You should make is the second word.

mosja- What food do they offer in the school's cafeteria?

That's fine in AE. Canteen would be used instead in BE.
