Yes, sound waves propagate in water at a speed of 1497 meters per second at 25 degrees C.
All sound waves, be that ultrasound or audible sound. Likewise water waves...
Sound waves cannot propagate in vacuum. Air is needed for sound waves to travel and there is no air in vacuum.
seismic waves
I can provide a partial answer. Sound waves differ from light waves in at least one crucial respect: a sound wave can only propagate through a physical substance - through "stuff". While a light wave can also propagate through a physical substance (e.g. glass), it can also propagate through a vacuum (a sound wave cannot do this). There are other differences as well, but perhaps other posters can provide those.
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.

Waves need a medium to propagate themselves through. The waves generated on a pond by a falling droplet need a medium, in this case its the very water of the pond. Sound waves can propagate both though a water medium or an air medium for example. Electromagnetic waves are an exception in that they do not need a medium to propagate through (the can propagate through the void of interstellar space).

Sound waves.
Sound waves cannot travel in space. Sound waves some medium in order to propagate.
No. At least in a gas and liquid, mechanical waves, including sound, can only propagate as longitudinal waves.
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.
Yes. For example, sound needs media (air, water, etc.) to propagate.
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.
Sound propagate in the form of waves. Waves have energy so they propagate through the medium. Unless you can reflect it back , or damp the sound wave using some or the other way, it is virtually impossible to "stop" a sound in mid air
