Your questions are valid :/ I knew Levy would save the day, but I imagined her using Solid Script: Air to form a bubble of air around herself and then pull Gajeel inside, or something similar. Levy's lungs holding more air than Gajeel's to the point that she can share her air didn't make much sense.
