The One God, creator of the universe and giver of the Torah. We don't utter God's name outside of prayers and reading Torah-verses.
The Jewish God is considered the Father of all. Just like any other religion, Jews show honor and respect to their God.
It is sign of respect to God (G*d or G_d)
because moses was send by God to free them from the slavery.
No. The kippah is a reminder of God's eternal presence. Some Jews also see it as a separator between themselves and God, or a sign of respect for God.
I don't understand the question but when Jews respect Shabat they thereby testify that the world has a beginning and its creator is our God.
The title 'Adonai' means 'Lord' and is a substitute for saying God's true name. Jews regard the name as too holy to pronounce (Talmud Sanhedrin, Mishna 11:1).
There is no record of such an attitude.
Jews believe in God the creator and in the Torah which God gave.
Abraham is not a god and Jews do not recognize him as a god. However he is considered a patriarch or father in the respect that he was the father of Isaac and through his seed came Jesus. One popular Bible scripture for Abraham is: James 2:23 And the scripture was fulfilled that says, "Abraham believed God, and it was credited to him as righteousness," and he was called God's friend.
With respect, the assumption in the question is not accurate. The Jews are not 'persecuted worldwide'.
Jews pray to God
Yes, same God for also Christians and Jews.
