Actually, "(T) Wing Cdr to (T) Group Capt to Wing Cdr to Act A/Cdr to Group Capt (WS) to Group Capt to A/Cdr".
So the first two are temporary ranks* (likely due to the lack of a permanent person filling the position during the rapid expansion of the RAF in 1940-42), and then he gets a perm posting matching his earlier temp posting.
This is followed by another temp (acting) position, then a "WS" (whatever that is), then two more perm-posts... both of which he has had before in temp/acting status.
* Or does the "T" stand for "training"... as in being trained for the position?
Or perhaps he commanded a training wing & group, not an operational one?
