Yes, it would stack since Algol affects the units' ATK stat shown when holding on a unit in a quest, while debuffs just have the icon. It hasn't been tested what Immensely lowers ATK of foes" reduces by, yet, but since ATK up Passives boost by about 40%, I'd assume that lowering ATK Passives lower by a bit less.
