The third sense (to work/function) is colloquial and common in Brazilian Portuguese. Often used with "bem" (well) or "mal" (poorly). In military or protest contexts, it's more formal. Common collocations include "marchar em protesto" (to march in protest) and "marchar em formação" (to march in formation).
