These are the few things that are clear with their ages: ▪Madara dead happened when Minato was the 4th hokage(?) ▪When Tobirama succeed Hashirama as the hokage, Hiruzen Sarutobi was still "young". Although its possible that he simple retire from that position. ▪Going by edo tensei logic (the person is resurected in the last condition they were by the time of their dead,although Kabuto managed to avoid that), Hashirama should have been at most in his latest 50 or very early 60.

Maybe out of topic: who was able to kill someone as OP as Hashirama in a battle ? Unless he simpled died of sickness or cancer.
