Do crayfish have spiracles?
No. The aquatic kind of spiracle (such as you'd find on rays and skates) could be located only on cartilaginous fish, or the most primitive of the bony fish. The loosest definition of spiracles seems to include a respiratory opening such as the blowhole in whales; lobsters do have ventral openings to the gills but these are anatomically dissimilar to those. (Also since lobsters are aquatic, they do not possess spiracles of the type you'd find on insects.)

Do arthropods and mollusks have lungs?
No for arthropods; yes for some molluscs. The larger aquatic arthropods like lobsters and crabs accomplish gas exchange using gills. Smaller ones like the land-based insects have holes (spiracles) in the exoskeleton and a tube system to facilitate gas exchange necessary for respiration. In this case, unlike mammals which use lungs to oxgenate blood which is pumped to the tissues, the tracheal tubes from the spiracles deliver oxygen directly to the tissues. Aquatic molluscs have gills for gas exchange whereas molluscs adapted to live on land like snails do have a lung.
