The caps, 20, 22, 23, 24 are all mica caps and probably are ok. Although, micas have been know to go bad now and then.
If there is any problem aligning or tacking or setting pushbuttons, then they should be replace with newer silver-micas types.
Resistor 25 (33K in the pushbutton gang area) should also be checked for out of 20% tolerance and repalced if it's out of spec, just like all the other resistors in the set for proper performance and restoration longevity.
