No Io does not have dirt or gravel.
Since nobody has ever been to Deimos, scientists aren't certain whether or not it has dirt or gravel. However, since both dirt and gravel are created by the action of wind and water, it seems likely that Deimos does not have these things, since it lacks both liquid water and an atmosphere.
We know next-to-nothing about the surface of Saturn. We can guess that something at least resembling gravel exists there, because it exists on Saturn's moon Titan.
It depends what you mean by dirt and gravel. On Earth much of the weathering which produces them depends on water. There is no nutrient rich equivalent of soil, nor water-rounded pebbles, but there is dust and breccia. (Breccia is composed of small fragments of broken rock), both of which probably result from micrometeorite impact.
none it is made up of ice and rock... you could call it gravel but it isn't the same... pluto's surface is made up of ice and rock material.. even a little gas

Yes, dirt

No, a cubic yard of gravel will have a different volume measurement compared to a cubic yard of dirt because they have different densities. Gravel is denser and heavier, so it will take up less volume than dirt in a cubic yard.
dirt gravel because it has some nutrients in it and gravel does not.
