Here you are using extra-offset on the RehearsalMark. extra-offset
is for last resorts, and the reason is exactly what you are experiencing:
it acts after LilyPond has done all its spacing, just before outputting
the object, so it completely bypasses the formatting engine. Because of
the multi-measure rest number "3", the mark is placed higher by default
in the first case (solo euphonium) than in the others. Then you ask
LilyPond to put this mark lower, which causes the collisions. Instead,
use something like

  \once \override Score.RehearsalMark.padding = 0
  \once \override Score.RehearsalMark.outside-staff-padding = 0

padding is the minimum distance from the staff, while outside-staff-padding
is the minimum distance from any object, including the staff.

Best,
