No, that title is "Caliph", not Czar.
After the death of the Prophet (SAW), Hazrat Abu Bakr Siddique (RAU) was chosen the Muslim Ruler. His title was 'The Caliph of the Rasool'. All the subsequent Caliphs were called Ameer-ul-Momineen. The title is generally called 'Caliph'.

No. The title taken by Muslim rulers who assert religious authority is typically Caliph or Ayatollah. The Czar was a term used to designate the Russian Kings.
There is no " Muslim tribal chief." You probably mean sheikh (best pronounced "shike" or "shake" but also "sheek"), which is the usual title for the leader of an Arab family or village, i.e. a tribe. The word is not a Muslim title. It simply means "old man." An Islamic spiritual leader is called an imam, which is not a tribal title.
