Until the 4th Databook comes out, here is what I think about the age of some characters.
Mei (early 30s)
Ay (early 50s)
Onoki (late 70s - early 80s)
Hashirama (early 40s when he died)
Tobirama ( mid 40s when he died)
Madara ( early 40s when he "died" - early 100s when he officially died)
Minato ( late 20s)
Nagato ( late 30s)
Kitsuchi ( early 40s)
Mifune ( early 50s)
Darui ( mid 20s)
Shisui ( mid 20s)
What do you think? Anyone to add?
