A kilogram of sand takes up much less space than a kilogram of feathers because sand is denser than feathers. Density refers to how much mass is contained in a given volume. Since sand particles are heavier and more compact than feathers, they occupy less space for the same mass.

No. The litre is a measure of volume, so your question cannot be answered. Try this... Would a litre of marbles and half a litre of sand occupy 1.5 litres? No, the spaces between the marbles would be filled with sand, so the total volume will be a bit less than exactly 1.5 L.
Put them in water.
The denser the material the faster sound will travel. Maple syrup is denser then sand.
No, it is a mixture.
