Why would any Jew (or Christian for that matter) live in Iran voluntarily?
Mizrahi.
Most left. Back in 2012 I was with a group that had an Iranian Israeli tour guide for 3 days. Her family left Iran after the revolution in 1979.
The Jews have lived there generally peaceful 2500 years.
The Christians of all stripes are allowed to live and worship freely. Proselytising is banned though and conversion from Islam is banned. But the life of Christians and Jews in Iran is better than any place in the Islamic world besides Lebanon.
