It depends on what's around. If the things are falling in a vacuum they all fall at just the same rate.
If things are falling in air, friction with the air slows them down. That's most important for small, light objects.
said that when Galileo dropped two metal balls from the leaning tower
of Pisa, the heavier one landed an inch or two ahead of the lighter
one. That would be because air friction slowed the lighter one a little
