Yes.
At a Jewish funeral home or synagogue or at the graveside.
There are two answers. In modern usage, the central room of a synagogue, where prayers are held, is called a sanctuary. And in ancient times, the same word referred to the Holy Temple.
Any celebration can be held at a synagogue, but any place can easily become a synagogue. In Greek, synagogue literally means "meeting house." Most Jewish celebrations tend to be held at a local synagogue, but celebrations can be held anywhere Jews can gather. During the Holocaust, Jews even had small celebrations in concentration camps.
Three.
In the Holy Ark in every synagogue (Jewish house of prayer).
That depends on whether the boy's Bar Mitzvah is held in the chapel or sanctuary of the synagogue.
Although the circumcision ceremony can be held in a synagogue, the normal location is in the home.
Either, or neither, there is no requirement for weddings to be held in synagogues and many Jewish couples choose other locations for the ceremony.
Usually in a synagogue, but a Jewish prayer service can actually be held almost anywhere, as long as there are at least 10 Jewish people participating.
Unless there is some specific agreement between the synagogue and the relevant Christian congregation (such as a synagogue allowing Christians to pray in the synagogue on Sundays while the Christians' church is in repair), church services do not take place in synagogues. If by "church services", you actually meant "religious services," Jewish services in synagogues are held three times per day; in the morning, afternoon and evening.
The sanctuary, where prayer services are held is the most important room, and within the sanctuary, the two most important places are the bimah, the raised platform from which the Torah is read, and the ark, the chest where the Torah scrolls are stored when not in use. It's fair to say that the ark is the most important place. Certainly, the ark is the focus of the sanctuary.
Wrong. The seder is held at home, and the special festival prayer-services are held in the synagogue.
