Of course!
Perhaps not, but evolution can exist without natural selection.
Because all animals that exist have formed, and are being formed and re-formed, continuously, primarily by natural selection.
They evolved by a process of natural selection.

No - natural selection does not create new alleles. Variation in alleles needs to exist in the population in order for natural selection to occur. Natural selection will involve the change in allele frequencies over time, but it does not create new alleles. New alleles are the result of mutations.
In all natural processes, there is an element of chance. In natural selection, most of that chance is introduced by the randomness of the genetic variations it works with. But other elements of chance exist as well. Natural selection is a stochastic phenomenon: not every less able variant will produce less offspring than the more able variant; much depends on chance environmental circumstances.
Adaptation does not allow for natural selection: natural selection causes adaptation.
The prefix of natural selection is "natural" and the suffix is "-tion".
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
