1) It means that its location on the H-R diagram is along a certain curve; the curve which contains most stars.
2) This, in turn, is a result of the fact that the star currently gets most of its energy by fusing hydrogen-1 into helium-4.
By nuclear fusion - converting hydrogen-1 into helium-4.

When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.

Assuming you mean a "main sequence" yellow star, it's a white dwarf star. In the end that fades to a black dwarf.
It is a sequence of numbers such that the ratio of successive terms is a constant.

The meanings of those two words are very similar. In an astronomical sense, the primary of a planetary system is the star (in the solar system it is the sun, which is also a star). Of course, the star is the main object in a system, in that it contains most of the mass, and is the most visible.
