Hats and Caps

No. You don't have to be orthodox to wear a yarmulke. In fact, you don't have to be Jewish. Some modern liberal Jewish congregations have pronounced the yarmulke optional during services or have dropped it completely, but it is still primarily a matter of individual choice. There are even some Jews who are quite secular, do not regularly pray or attend synagogue services, but who wear the yarmulke in general daily life.

A fez is often considered a crown due to its symbolic significance and cultural heritage. Traditionally worn in various cultures, particularly in the Ottoman Empire, the fez represents status and identity, much like a crown signifies authority and nobility. Its distinctive shape and vibrant colors can convey a sense of pride and belonging, elevating it beyond mere headwear to a symbol of cultural esteem. Therefore, a fez can be viewed as a crown that reflects cultural identity rather than royal power.

The word 'kippah' is the Hebrew name for the skullcap worn by Jews. Saying "Jewish kippah" is redundant as a kippah is a Jewish item.

Another Jewish name for the kippah is "yarmulka", a word which is used in America and by Yiddish-speakers. The word "yarmulka" goes all the way back to the Aramaic; and it translates to "fear of the King"; because the skullcap's purpose is to remind us of God's presence.

In certain countries, it is believed that the crest on the beret is designed / shaped in a way to ward off evil spirits. The crest is sometimes blessed by holy men for the same effect.

Jewish males cover their heads with a kippa and/or a hat, as a reminder of the presence of God. The Yiddish word for kippah, "yarmulkah," is a contraction of the Aramaic "yerei malkah": to be aware of the King.

Women are seen as less tempted by sin as are men.

Note that Jewish married women traditionally cover their hair (Talmud, Ketubot 72b). This is for the purpose of modesty - only her husband should see her beauty - since the hair is considered beautiful (Talmud, Berakhot 24a).

It is unknown. There is no mention in the Torah of Abraham wearing a kippah.

In traditional Judaism only men wear a Yarmulke (or Kippah) because only men are obligated to fulfill the timebound commandments of prayer.

Turban or 'Pagri'

The answer to this question depends on why a Christian wants to wear a kippah. In the Jewish tradition, Kippahs are worn as a show of respect for God. Christians have different ways of showing respect for God as well. So no, it's not disrespectful for Christians to wear kippahs if they are in a Jewish ceremony or environment. But it may be best to ask the person in charge if it's ok.
