That is short for Hertzsprung-Russell diagram. It is a diagram in which the brightness of stars is plotted against their surface temperature (which can be deduced from their color). It turns out that most stars (basically, the ones that get their energy from fusion of hydrogen to helium) are on, or close to, one particular curve in the diagram - the so-called "main sequence".
Up at the top right. If you look on the Australian Telescope National facility website, their HR diagram shows this clearly.
Slightly to the right of centre on the main sequence. If you look on the Australian Telescope National facility website, their HR diagram shows the position of the sun.
White dwarfs.
The two ways are by their surface temperature (spectrum) and by their absolute magnitude (intrinsic brightness). The HR diagram has spectrum along the horizontal axis and absolute magnitude along the vertical axis. Each star occupies a point in the HR diagram.
because it is fun
Of course they are on the HR diagram. They are simply not on the main sequence.
The HR diagram contains only stars - so everywhere.

The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
its located somewhere
All stars.
the purpose of the venn diagram is to know what are the differences and the similarities between them.

The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
Its called an HR diagram or a Hertzsprung-Russell diagram.
