no, they fall the same acceleration ( one gravity ) neglecting air resistance; however they may reach different velocities with air resistance.
A heavier pendulum will swing longer due to its greater inertia.
I'm not exactly sure what you mean when you say "heavier" and "lighter". Does that mean the object's "weight" ? Could that be the same as the gravitational force on it ?
Yes. The acceleration depends on the aerodynamics of the shapes of the objects - not their mass.

If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen
It usually has greater capacity for fuel storage.
