Orthodox Jews will always wear a Kippa (Yarmulke) and/or a hat to cover their head. Others will typically wear a Kippa when they enter the synagogue or participate in other religious ceremonies.
Among non-Orthodox Jews, some wear a kippa while in synagogue and Hebrew school.

Jewish males cover their heads with a kippa and/or a hat, as a reminder of the presence of God. This practice is twice mentioned emphatically in the Talmud (Shabbat 156b; Kallah 1:16), in statements dating back 1700 and 1850 years, respectively. Even then, covering one's head is spoken of as an established practice, not something new.
The Yiddish word for kippah, "yarmulkah," is a contraction of the Aramaic "yerei malkah": to be aware of the King.
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).
There's no prohibition against non-Jews doing so.
You would wear a kippah on your head; it is a form of skullcap. Religious Jews wear them everywhere they go, while some less-religious Jews wear them only in the synagogue.
Jewish-style kippahs are generally worn only by Jews. But according to Jewish law, a regular cap or hat may serve the same religious function as a kippah.

The kippah (also known as a skull-cap or yarmulka) is worn by men of any Jewish denomination. Orthodox men wear the kippah all the time. Non-orthdox men (and some non-orthodox women), usually wear it only in a synagogue or at home during Jewish events. Some Reform Jews wear a kippah all the time.
No. The kippah is a reminder of God's eternal presence. Some Jews also see it as a separator between themselves and God, or a sign of respect for God.
On the top of the head. (Anywhere else it would fall off).
Jewish men are commanded to cover their head in respect to God at all times, especially while praying, or at a religious event or service. The main form of head cover is a Kippah, or Yalmukah. However, only Orthodox Jews wear Kippahs at all times. Most Reform, Conservative, and some Modern Orthodox Jews do not wear kippahs at all times, and only wear them while at Temple, or another religious event.
Most Orthodox and Ultra-orthodox Jewish men wear a kippah all the time. Married women in this group also cover their hair in public. Some non-orthdox Jews also wear a kippah all the time, particularly some rabbis and cantors.
It is unknown. There is no mention in the Torah of Abraham wearing a kippah.
No, it`s not proper for a Gentile to wear a kippah all the time as this is a Jewish tradition that doesn`t apply to non-Jews.
they wear it to show others and themselves that there is a G-d above us
No. Judaism calls for covering the head but does not specify the type of head-covering. Religious Jewish males usually wear a kind of cap (kippah; yarmulka) and/or hat.
