These minerals are called evaporites.
Chemical weathering processes change the mineral composition of the rock, but physical weathering processes do not. Mechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry. Chemical weathering is the dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process. Warm, tropical climates are ideal environments for chemical weathering to take place as the chemical reactions are quickened by the bountiful rain and warm temperatures.

Sulfur is a chemical element (S) and doesn't contain any other mineral.
A metal is a chemical element, any other mineral.
They can be called chemical sedimentary rocks, or evaporites; such as rock salt.
Hydrolysis is one chemical process that accomplishes chemical digestion. There are other chemical and mechanical digestive processes.
Each mineral will have its own chemical composition (with small variations) apart from other minerals.
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.

No. Pure cobalt is not found in nature, only in combination with other elements, and is therefore not considered a mineral, but a chemical element.
The color is derived from the chemical composition of the mineral, or from staining or inclusions of other minerals.
