they fall at the same time in the absence of air resistance . But in the presence of air resistance , the hammer falls faster because it has a greater mass and the feather is slowed down by the air resistance due to its less mass.

lets say it depends on the surface area and both the mass of the object

AND lets say the difference in the time taken to fall is hard to recognise because it may have 0.01 second differences .. so we use specialized instruments for the task.
