It's said on major Jewish holidays.
Yizkor is a special memorial service honoring those who have died, and is held on certain festivals.
I think it's a table where Jewish people sit and say the Yizkor prayer.

Yes, near the end of the holiday.
Yes. It's called Yizkor.
Yes. The Yizkor service is a brief service conducted in the synagogue on four occasions during the annual Hebrew ritual calendar, during which one's deceased immediate family are memorialized (parents, children, siblings, spouse). A member of the congregation who has lost none of these relatives normally exits the sanctuary while the Yizkor service is recited. The departure is temporary, and typically lasts 10-15 minutes or less.
There are several Jewish prayers that respond to death. There is the memorial prayer, "El Malei Rachamim" (God, full of mercy) that is said in the specific form for the decased individual at funerals and said collectively for all of the deceased at Yizkor services on Yom Kippur and the pilgrimage festivals. There is also the mourner's Kaddish, said by the immediate mourners starting at the funeral and continuing for 11 months, and then at Yizkor services thereafter. Also, before a person dies, if the person is able, the person should say the "Vidui," a prayer of confession, followed by the "Shema." When a Jew hears that someone has died, the traditional blessing is "Dayan Emet," praising God as the true judge.
The main Jewish prayers for the dead are Yizkor and Hashkava (also known as El Malei Rahamim). Kaddish is not a prayer for the dead (though laypersons often call it that). It is a praise of God, said by mourners as a good deed for the deceased person's merit.
I think it only applies to Orthodox Jews. I'm Reform, and we stay inside the chapel or sanctuary and read Psalm 23.
Yes, Yizkor (prayer for the dead) is recited on Yom Kippur and on the last day of each of the three major festivals. Some also recite a short prayer for the dead on Shabbat.
