Hackett in ME3 was 52, Anderson in ME3 was 49, Helena Blake is definitely up there in age as is Zev Cohen. Chakwas I'd estimate is roughly about in the same age range as Anderson and Hackett. Garret Bryson, considering the Prothean Ruins on Mars were found in 2148 would mean that he would have to be at least 38, but since he remembers when aliens were a myth, that would roughly make him around 50-60 approximately. Udina I'd estimate would be around the age group of Hackett and Anderson, maybe a bit older.
