So called Islamic schools

Q: Kindly favour me with your reply to the following queries: 

  1. Is it competent and permissible in terms of the Shariah fiqh regime for a disbeliever (kaafir) to be appointed to the position of principal or head of an Islamic institution? Having regard to various verses of the Quran, including but not limited to those in Surah Maaidah,I was always of the view that the Shariah proscribed such an appointment.
  2. Is it permissible in terms of Shariah for an Islamic institution to observe a period of silence at an assembly of its students as a mark of respect for a disbeliever who recently died?
  3. Is it permissible in Shariah to for an Islamic school to honour a disbeliever on the occasion of his birthday by singing of 'happy birthday' wishes and greetings at an assembly of the school population? 

Making an effort to respect teacher

Q: One of my teachers does not talk to me because of some misunderstanding which was not my fault. I tried to explain to hime but he did not believe me. Now when I see him while driving, I put my hand up to greet him but he does not respond. I also see him in the supermarket but he just walks past me. I said salaam in a loud tone but he did not reply. My question is that as a Muslim is my duty fulfilled by trying to talk to him and if I see him I would make Salam or put my hand up. Will I be sinful because he does not not talk to me? Have I done my duty?
