The Creator has one true name which is represented by the letters YHVH in English. The Hebrew letters are "yud, hei, vav, hei". These four letters are referred to as the tetragrammaton and are a contraction of the Hebrew words for, "was, is, and will be". His true name was only said in the Temple and with the Temple's destruction we lost the correct pronunciation.
In the Tanach (Jewish Bible), there are 72 different 'names' used for The Creator, these aren't actual names though, they're descriptions of Him that are contextual. In daily conversation, most Jews use the name 'HaShem' which literally translates to 'The Name' in reference to His true name.
HaShem is a polite way of referring to God. The word HaShem is used when not praying.
The term "Ha Shem" in Hebrew means The Name. This is a very delicate way of referring to God, by those who consider the name of God to be too holy to actually utter.
The religion that synagogues are associated with is Judaism.
From the Jewish perspective, all Nations are different in the eyes of HaShem (The Creator). The Jewish Nation is just one of the different nations with its own path to HaShem.
We have 1, we worship HaShem, the creator.
To be Jewish can mean you either practice the Jewish religion, or are from a Jewish decent. It is both a race and a religion. Someone that is culturally Jewish may not practice the religion, but has a Jewish heritage. Likewise, people that do practice the Jewish religion do not have to be culturally Jewish, or have Jewish ancestors.
Jews believe in G-D a.k.a. Hashem the one and only!
No, according to Judaism, HaShem (The Creator) is not man or son of man.
There aren't areas of the Jewish religion.
First, there's no such thing as a "Christian Jew". As the teachings of Christianity directly oppose those of Judaism, following the teachings of the two religions is impossible. Second, Passover is a Jewish holiday that remembers both the Israelites accepting HaShem (The Creator) and HaShem redeeming the Israelites from slavery in Egypt to lead them to the promised land. HaShem specifies that every generation of Jews are to observe the holiday of Passover in the Tanach (Jewish Bible). If, by "Christian Jews" the questioner is referring to Jews who have converted to Christianity, according to the teachings of Judaism, any Jew who converts to another religion has cut themselves off from the Jewish Nation and HaShem. As a result, they would not legitimately be able to participate in Jewish religious observances unless they were to repent and return to Judaism.
In Yiddish they say Eibishter or Hashem for G-d, though there are many words including Got and Adoshem.
According to Judaism, a prophet is a person through whom HaShem (The Creator) communicates. There is no requirement for prophecy to be about the future in Jewish tradition.
We don't worship prophets, we only worship HaShem, the creator.
No, from the Jewish perspective, it would be impossible for HaShem to die as He is not a person.
