No, from the Jewish perspective, it would be impossible for HaShem to die as He is not a person.
yes
Judaism was the first to teach the existence of One God. Jewish tradition is that the entire Jewish nation, two million strong, heard God utter the Ten Commandments on Mount Sinai. Judaism does not teach that all members of other religions are automatically doomed.
What you say is true about Islam and Judaism and Catholicism: all come from the one God. Only Catholicism is based on the coming of God as man, Jesus, the son of God, who always was one with God the father and God the Holy Spirit. Catholicism does not teach against any other religion
Ethical monotheism. The belief and worship of One God, and the ethical system of conduct which that implies. See also:Who created Judaism?Jewish contributions to society
How is the nature of God in Judaism different from God in Christianity
There is only One God in Christianity, Judaism and Islam.
No. Reform Judaism started in Germany, in the 19th Century.
The One God, who created the universe, is the only God of Judaism.
All three religions teach that there is only one God. The nature of that God is not the same in the three religions, though.

in judaism, shekinah is the glory of god. She is also the female aspect of God in judaism.
This question is too vague for a complete answer. Acknowledging that, I'll say that Judaism is the first known religion to recognize that there is but one true living God.
