Noah lived 950 years.
Enos, Cainan, Mahalaleel, Jared, Methuselah and Lamech were all alive when Noah was alive.
Yes, Noah had three sons, Shem, Ham and Japheth
Methuselah, Lamech, their wives and children would have helped Noah build the Ark, along with Noah's wife and sons, and possibly the children and grandchildren of Jared and Enoch.
Noah spent the last 350 years of his life sharing the oral history of all that had taken place before the Flood. And he would have continued to prophesize, evangelize, and warn the people to live their life in honor God.
God chose Noah because he was the only righteous man in the 10th generation who kept himself clean and undefiled from the world around him and was spiritually mature and obedient to God.
Noah walked with Shem, Arphaxad, Salah, Eber, Peleg, Reu, Serug, Nahor, Tarah and Abraham.
