On Earth, no. Air resistance would slow the feather way down.
However, dropped on somewhere without an atmosphere (like the moon), they would reach the ground at the same time.
To magnetize an iron nail permanently, you would need to stroke the nail along a magnet multiple times in the same direction. This process aligns the domains in the iron, creating a magnetic field along the nail. A diagram would show the iron nail being stroked along the magnet in one consistent direction to align the domains.

A lever, like a claw hammer or a pry bar, would be most effective for removing a nail from a piece of wood. Lever action can amplify the force applied to the nail, making it easier to pull it out.
A nail in your shoe
If you hit the nail with the hammer, it will drive into the wood, securing the two pieces together. The force from the hammer will cause the nail to penetrate the wood, creating a strong connection between them.
They weigh the same.
They are both 1 Kilo. So, no.
As the rust expands the nail will get slightly bigger then reach a point when starts to disintergrate.
Nail it to the ground or cement it to the ground.
It would have nail polish on it.
No, obviously the larger nail is bigger so it would have more mass.
That would depend on how big the nail was and what it was made out of.
The mass of the iron nail remains the same when it is ground into powder since mass is a conserved quantity. The only change is in the physical form, with the nail being broken down into smaller particles.

The Nail art
Would be the nail root, because it is the potion of the nail that is buried in a fold of skin.
A nail made of liquid or gas would not be very effective. The hammer would go right through it. So, nails have to be solid.
