"Gasp" means to inhale suddenly and with difficulty, typically from shock, surprise, or exertion. "Pant" means to breathe with short, quick breaths, usually from physical exertion. "Puff" means to breathe in short bursts or with effort, similar to gasping. Both panting and puffing involve quick, labored breathing that parallels the action of gasping. "Huff" is more about expressing annoyance, and "blow" is a general term for expelling air.
