I have my own speculation but not sure if I am correct. So tell me what you think.

As long you are on the same planet (and same distance away from the planet) the gravitational force is the same. For Earth, it is about 9.8 m/s^2. An object of 10 kg, irregardless of what it is made of, will have a mass of 98 N.
Now if you drop the 10 kg piece of iron and 10 kg of wood, the iron will do more damage to the ground because:
a) it is denser
b) it has less elasticity, whereas wood will absorb some of that energy.
This might be the reason why people might think 10 kg of iron is "heavier" than 10 kg of wood.
Now, some may bring up the argument that there is a magnetic attraction between the earth's poles and the iron. This would be so infinitesimally tiny that it would make a difference.

No. Gravity depends only on the masses of the two objects and the distance between them. I assume you're talking about the gravity affecting the object here on Earth, so one object is the Earth, and the object is at a distance of Earth's radius from the planet's center, so those are constants. If the iron and the wood have the same mass, then the force of gravity on them is equal. The sizes or densities of the objects have no effect on this scale.

No it is now, gravity is always uniform on same mass... Voume & material wont matter...
this can be proved by the famous experiment of dropping a rubber and iron ball of same mass from a tower.... if considering air friction as negligible both wil hit ground together...

force of gravity is independent on every object. when u drop two of different masses from higher potential the bigger will strike the ground first because of air friction and atm pressure which is low on the bigger then the smaller one

The force of gravity is the same on both.
However a lb of gold doesn't weigh as much as a lb of feathers... While an oz of gold weighs more than an oz of feathers.

No, it will be the same... One would fall faster than the other because the higher density would result in less air resistance to slow it down...
