1.5 Kilos. Since the moon's gravity is approximately one sixth of that on the earth - divide the 9 by 6 !
No, a bowling ball (or any other object) has exactly the same inertial mass no matter where it is (its actual inertia will, of course, depend upon its velocity as well as its inertial mass). Weight changes on the moon, but inertia doesn't.
No, Unless you put force behind them, neither. The lower gravity would cause them to just sit there were you let go of them. But if you did put force behind them; the bowling ball would hit the ground first, solely because of its weight and momentum.
There is a very easy analogy for how gravity works. Everything in the universe takes place within spacetime. Imagine spacetime as a trampoline. Where mass exists, spacetime becomes curved, just like a trampoline would become curved if one were to place a bowling ball on it. We as people fall down the curves made in spacetime, but the earth keeps us from falling any further, thus we are stuck to its surface. If one were to put a ping-pong ball on the trampoline, it would fall down the curve made by the bowling ball. It would stop once it hit the bowling ball, and be stuck to its surface. There are a few subtleties to this model that keep it from working perfectly, but this is basically how gravity works.
my prediction about the bowling ball falling first was true.
For example take a bowling ball and a bouncy ball... Sure the bowling ball has more mass so the pull of gravity is greater on that object but this also means the surface area of the bowling ball causes air resistance thus slowing it back down. The bouncy ball on the other hand has less mass and is thus effected less by gravity but its surface area is much less so it "pierces" through the air because it has very little air resistance. Hope that helps :) Another opinion: In a vacuum all objects fall at the same rate. The only thing that causes objects to fall at different rates on Earth is their aerodynamic shape. To demonstrate this the astronauts on an Apollo moon mission (Apollo 15 maybe) dropped a feather and a hammer. They landed at the same time, because there is virtually no atmosphere on the moon. On Earth the feather would tend to "float" down, riding on air.

Gravity does not affect total mass, no matter where in the universe the bowling ball travels. Therefore, a 7 kilogram bowling ball will always be 7 kilograms.
7 kg is also known as 7 pounds. :)
The maximum weight a bowling ball can be is sixteen pounds.
2.2 kilograms per pound, so 7x2.2 is 15.4 lb
The maximum weight of a typical Candlepin Bowling Ball is 2lb 7oz.
A 16 pound bowling ball would be 71.172 newtons in weight.
The cover stock composition, the surface texture and the configuration of the weight in the core.
The instrument used to measure the diameter of spherical objects is called calipers.
Weight!
