The word "solution" implies that there is a solvent and a solute involved, which simply means they are mixed together. Whether or not the solute actually dissolves -- that is, decomposes into different chemical compounds from the original -- depends on the substance and the solvent being used.
Usually a solution will be aqueous (liquid) in nature, but strictly speaking doesn't have to be liquid.
It is true that temperature can affect solubility of various substances. Sugar, for example, dissolves more readily in hot tea than in cold tea.
But the solubility of a substance at a given temperature depends on the substance itself. This sort of question is answered by chemistry, and there are various rules for determining how soluble a substance is. You can look up "solubility rules" for more detailed information on this.
There are countless millions of chemicals that dissolve in hot water (or even in cold water). I don't know why you think there are only two. Water is a tremendously versatile solvent.

The two minerals dissolve in hot water to form solutions are sugar and salt. They will form a homogeneous solution as they completely dissolve in water.

No, talcum powder will not dissolve in cold water. Talcum powder is insoluble in water, meaning it will not mix or dissolve in water at any temperature.
Instant coffee granules dissolve faster in hot water than in cold water.
Most chemical salts dissolve faster in hot water than in cold water.
They are called solutes.
Yes
Cold water
Jelly will not dissolve in cold water. Instead, it will remain mostly intact because the gelatin in jelly requires heat to break down and dissolve. Cold water does not provide the necessary temperature to effectively dissolve the gelatin, so the jelly will maintain its structure.
It depends on the kind of the solid
