I blow a balloon full with air.
If I then inhaled it back in and let it flow back in my lungs, all at once, would the amount all go in the lungs and destroy them (since not all the air could possibly fit in)?

Maybe not a balloon, but air expansion can cause injuries in scuba divers if they hold their breath when surfacing quickly from a depth.
Yeah, I’ve heard of that too.
In this example however, both blowing the balloon and taking the air in would happen in the same room, under same conditions (temperature and air pressure).
Then: no. The amount of pressure from the balloon would only ever equal the amount ones lungs could generate in the first place. You’d have to be able to injure the lungs blowing up the balloon for the balloon too have a similar effect.
