Jehovah "set up a sign for Cain" to prevent his being killed, but the record does not say that this sign or mark was placed on Cain's person in any way. The "sign" likely consisted of God's solemn decree itself, known and observed by others.(Genesis 4:10-15)

Yes. Enoch was Noah's great grandfather. But there were more than one 'Enoch' in the Bible. There was Enoch who was Cain's son and Enoch who was Seth's (Cain's brother who was born after Cain killed his other brother Abel) great-great-great grandson. This Enoch was the one who 'walked with God' (Gen 5:24). Noah is related to both. He is the second Enoch's great grandson. (Gen 4:17, Gen 5)
Cain and Abel were Adam and Eve's sons. Cain killed Abel out of jealousy of his generosity.
No. Chronologically, Kayin (Cain) was earlier ... about as early as a person in the Bible could be. He was the son of Adam and Eve, a farmer, and the brother of Abel, who he killed. (Genesis 4:1-16) Tuval-Kayin (Tubal Cain) came 6 generations later, and was Cain's great-great-great-great-grandson. His parents were Lamech and Tzillah, and he sharpened cutting implements of copper and iron. (Genesis 4:19-22)
