Muslims is the same person Jesus of nazareth from the Bible and the Quran Isa son of Mary?

according to muslims why is jesus called Isa in arabic? according to the Quran Isa was elevated to Heavens.. because he escaped of the Crucifixion how come do you say there is nobody in heaven or hell? why is Mary called sister of Aaron in the Quran? did the Quran mention Miriam or Mary the Aaron's sister as the Bible said?
