The time spent by year was similar but Mourão Filho lagged behind. Tracking an earlier stretch of their careers:
>Kruel: 2nd lieutenant 1921, 1st lieutenant 1922, captain 1931, major 1933, lieutenant colonel 1943
>Mourão Filho: 2nd lieutenant 1921, 1st lieutenant 1922, captain 1931, major 1937, lieutenant colonel 1943
>Costa e Silva: 2nd lieutenant 1921, 1st lieutenant 1922, captain 1931, major 1937, lieutenant colonel 1941
>Castelo Branco: 2nd lieutenant 1921, 1st lieutenant 1922, captain 1932, major 1938, lieutenant colonel 1943
So starting from 1st lieutenant it's:

Kruel: 9, 2, 10, 4, 7, 5, 4
Mourão: 9, 6, 6, 5, 8, 6, 2
Costa: 9, 6, 4, 3, 8, 6, 3
Castelo: 10, 6, 5, 2, 7, 6, 4

Mourão's lag is concentrated in the lieutenant colonel - brigade general phase, precisely when he was under suspicion, Vargas' CoS brought up the Cohen Plan in 1945 and openly accused him in 1955.
Castelo's promotion to marshal doesn't mean much, he just decided to retire now that he was President. More important was his "promotion" to commander-in-chief. The bolder Costa e Silva promoted himself to Minister of War
>maybe that trip to Italy in WWII meant greater military nimbus
And not any random position:
