Adaptive change is the province of natural selection and natural selection is one of the main drivers of evolution. Natural selection selects from the individuals variations in a population of organisms on, basically, reproductive success and this adaption is passed on to progeny which changes the allele frequency in the population which is evolution.

Evolution is the change in allele frequency over time in a population of organisms. Natural selection, the adaptive driver of evolution, is the nonrandom survival and reproductive success of randomly varying organisms. Sure you did not mean the conditions under which this process happens? If so, let me know.
An individual organism does not lose characteristics. A species can, over time, and this is called natural selection, which thus results in evolution.
Darwin developed The theory of evolution by natural selection.So, to answer you question, all of it!You need to make a distinction between evolution, the change in allele frequency over time in a population of organisms, and natural selection, the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of evolution.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
The generally accepted theory of evolution by natural selection was proposed by Charles Darwin

it relies upon the population
To Darwin, the central concept of organic evolution was natural selection. He proposed that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring, leading to changes in the characteristics of a population over time.

Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
No. Evolution is the change in allele frequency over time in a population of organisms. This may be the result of stabilizing selection, but is still evolution.
