Because the marble is steel it has more mass making it more difficult to stop. Then the question is how rough or smooth is the surface? It will certainly travel further than the customary glass marble because it has more mass.
That depends on many circumstances including, projectile weight, catapult strength and etc.
higher inertial mass

Yes. The force applied by the catapult will cause an acceleration on the tennis ball that is inversely proportional to the mass of the tennis ball.

A marble has more mass than a piece of popcorn having a similar size, because the material in the marble is denser than popcorn.The atoms in the marble's elements are more closely structured, whereas the popcorn is an expanded carbohydrate starch with a substantial amount of liquid (water) and gas (air) inside. The marble was also already more dense than the unpopped kernel.
I'm pretty sure a marble has less mass
The mass of a regular size marble is 1.27 grams.
It would vary because marbles come in several different sizes. They also come in a variety of materials like glass, agate, flint, etc. The denser the material the more mass it would have. Therefor, a 3/4" marble of flint would have more mass than one the same size made of glass.
That depends on many circumstances including, projectile weight, catapult strength and etc.
What size marble? And is it made of marble or glass?
To achieve the most distance, you should set your catapult to release a projectile at 45 degrees angle relative to horizontal plane.Higher stored potential energy doesn't neccesarily mean more distance. Distance of the shot depends mainly on starting velocity, which in turn depends on rate at which catapult transfers the energy to the projectile. A limit for that depends on construction of the catapult.
All of the above? You can say the same thing in many ways. All of the following are different ways of saying the same thing, and all are correct: The marble sinks because the marble weighs more that an equivalent volume of water. The marble sinks because its density is greater than the density of water. The marble sinks because it has a greater mass than than same volume of water (and there is gravity/acceleration).
What do you want to measure about the marble? Its diameter, radius, circumference, volume, mass, density...?
Depends on the marshmallow and the marble... a 2g marble will have the same mass as a 2g marshmallow........
There are more but these are just a few: Aircraft Catapult, Slingshot Catapult, and an Onager Catapult.
