You should specify which movement(s) you're asking about; perhaps there's a difference.
The general rule is that if you're born Jewish, you remain so, and you can always return to your roots (as many young people have been doing in the last four decades). Jews who strayed and then return are able to become part of the normative Jewish community.
However, those who go over to other movements and make no effort to return, have a historical tendency to go lost eventually: this happened to many of the Ten Tribes (those who dabbled in idolatry), the Sadducees, the Essenes, the followers of the false messiah Shabbetai Zevi (in the 1600s) - and some other groups too.
The Shekinah is considered important in Jewish theology and tradition because it represents the divine presence of God among the Jewish people. It is believed to bring comfort, protection, and guidance to the community, and is seen as a symbol of God's closeness and connection to humanity.
The Jews are considered God's chosen people in the Jewish faith because they are believed to have a special covenant or agreement with God, where they are chosen to be a light unto the nations and to uphold God's teachings and commandments. This belief is central to Jewish identity and history.

Yes, Matthew, one of the twelve apostles of Jesus, is believed to have been Jewish.
No. Jewish tradition would give that title to Abraham.
Luke was not Jewish; he was a Gentile. Matthew, Mark, and John were Jewish.
All of the first Christians were Jewish. Jesus and his disciples were all Jewish.
According to Tradition, a person is Jewish if their mother is Jewish. If you do not know the religion of your mother, you are assumed not to be Jewish. Even in liberal movements that recognize patrilineal heritage, the person must also be raised Jewish. So if you weren't raised Jewish, you are not Jewish.
People are considered to be Jews if they convert to Judaism, or because their mother is Jewish. (In the Reform movement a person is considered Jewish if they have a Jewish father and are raised Jewish but don't have a Jewish mother.)
Jesus was a Jew so he probably believed in a host of traditional practices.
They're a regional food, not specifically Jewish.
No. But the Jewish people are considered the chosen people, though not all Jewish denominations share this belief.
