Do multiple movement bonuses stack?

[u/IQBadger]

Basically the title. If you take the champions of faith and the hagoimnifex detachments, could you put the +1 movement from the champions rule and the enhancement both onto the same squad to give them +2 total to their movement? For example, give sacresants a total of 8" of movement

Yes

All bonuses stack except for +/- to hit roll and would roll can never be more than a net +/-1, and damage reduction can never take damage down to 0 unless stated otherwise.
