Which rock? Any liquid that is dense enough will support a rock; the most common would likely be Mercury, in which even iron floats.
Pumice rocks have been known to float across oceans.
Vessicular Rocks. Eg Scoria and Pumice.
It depends on the type of rock. A rock like sandstone would not sink if it is a small peice. Small rocks can float. That's when its called silt.

You can't float but you can fly. (Floating implies liquid, and Pluto has no liquid that we know of).
The liquid which is less dense will float on top of the liquid which is more dense. Density affects the liquid's level.
Solid iron will float in liquid mercury. In most liquids it will sink.
An object will float if it has less density than the liquid in which it is placed.
No
