It is unclear what the "other" religions are from the perspective of this question. Please read the Related Question which discusses all three major religions that make claims to Jerusalem. All other religions are not affected by that city except tangentially through the three monotheisms.
Jerusalem
Jerusalem, for Christianity, Islam and Judaism
The three religions and a major reason for their presence in the city are: Judaism (Temple Mount), Christianity (site of the crucifixion of Jesus Christ), Islam (Dome of the Rock)
The three major world religions that originated in the Middle East and have ties to Jerusalem are Judaism, Christianity, and Islam. Jerusalem is considered a holy city by all three religions, with each having historical and religious significance in the region.
Jerusalem certainly has holy sites of the three major monotheistic religions and adherents of those religions living within its walls, but depending on how "home" is defined, this may or may not qualify. The leadership of all Christian Churches and all Islamic Mosques in Jerusalem are governed by councils operating outside of Jerusalem, so the homes of those religions can be as far away as Rome, Addis Ababa, or Mecca. Based on that, only Judaism has its home and central apparatus in Jerusalem. Other religions have a presence and wonderful sites, but not a home, even if the people of those religions have made Jerusalem their home.
