both!

Assuming that each object is held with its center of gravity at the same height, and that each is dropped cleanly, with no rotation induced, the one whose lowest part is closest to the ground when dropped will hit first.
They would hit the surface together, after a very long time. Gravity on Ceres is pretty light.
Assuming no air friction, neither and no it would not be different. In real life, I imagine the brown trout would hit first.
About 8 kilometers above the ground.

as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.

They will both hit the ground at the same time.
Assuming both were dropped from the same height above ground, in a vacuum both would hit the ground at the same time. In a significant atmosphere (e.g. average ground-level on Earch) the bowling ball would hit the ground first.
19.6 meters / 64.4 ft
If dropped from the same height, they will hit the ground at the same time.
The higher the height the ball is dropped from, the higher the height it will bounce to.
