Yes. The Kurds are an overwhelmingly insular community.
Kurds should have their own country because their identity is under siege in Turkey and Iran and they have been subject to genocides in Iraq. The only people who look out for Kurds are other Kurds, not the national governments of the countries in which they live.
If it has happened? Yes. If it's common? No. Most Kurds marry within their own ethnicity and in some rare cases with the surrounding ethnic groups with whom they share common religion.
Yes, but there are minorities of Shiite Muslim Kurds, Yazidi Kurds, and Baha'i Kurds.
Most Kurds are Muslims, so yes. There are a minority of Kurds who are Yazidi or Zoroastrian which are henotheistic faiths and not strictly monotheistic. There are also Kurds who are Atheists.
No. There are currently ~35 million Kurds.
Arabs are more, kurds are about 17% of Iraq, they are about 4-5 million kurds in Iraq (there are more than 20 million kurds in the world), the kurds grew more and more powerful in Iraq, now the president of Iraq is a kurd.

Kurds are only troublesome for Iraq because Iraqi Arabs are not interested in recognizing that the Kurds are a unique and different people from them but still worthy of respect. Iraqi Kurds, generally, have better statistics (quality of life, lifespan, less insurgency, more tolerance, more scientific and business acumen) per capita than Iraqi Arabs. The problem comes from the Arab side vis à vis Kurds, not the other way around.
NO. The Arabs are the largest ethnic group in Southwest Asia. There are at least 150 million Arabs in the Middle East, whereas there are only 35 million Kurds.
Kurds are members of a mainly pastoral Islamic people living in Kurdistan.
There are around 6.5–7.9 million Kurds in Iran and 6.2–6.5 million Kurds in Iraq, so there are more Kurds in Iran. However, as the Iranian population overall is significantly larger, Kurds make up a more significant percentage of the population in Iraq.
Generally, No. Of the overall 35 million Kurds, there are less the 35,000 Christian Kurds, which makes Christians less than 0.1% of the Kurdish population. Understandably, Christian Kurds celebrate Christmas, but Muslim, Jewish, Yazidi, Zoroastrian, and non-religious Kurds do not celebrate Christmas.
