Absolutely pure water is not even that. Water dissociates itself into dissolved hydroxide and hydrogen ions, the latter forming hydronium. It is thus a solution of both of these ions.
Yes, pure water can be classified as a solution because it is a homogeneous mixture of water molecules.

Pure water is the standard for a neutral fluid (neither acidic or basic.) Ammonia is a basic solution.
It is a solution. A very dilute solution, as it is almost entirely water, but in actual fact there is no absolutely pure water anywhere in the world -- even double-distilled water will contain some silicon dioxide in solution from the glass or quartz tubing in which it was distilled.
Water is pure, not a solution.

No. Pure water is a compound, which is a pure substance. A saltwater solution is a mixture of water and salt, and is not a pure substance.

Pure sugar is a compound, which is a pure substance. If you dissolve sugar in water, you will have a homogeneous mixture, which is a solution.
Adding pure water to an acidic solution will dilute the solution, causing the pH to increase. This is because the concentration of H+ ions, which determine the acidity of the solution, decreases as more water is added.
By evaporating the water of the solution and condensing it.
