60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr

The HR diagram contains only stars - so everywhere.
Of course they are on the HR diagram. They are simply not on the main sequence.
The majority of stars in a Hertzsprung-Russell (HR) diagram are located along the main sequence, which runs diagonally from the upper left (hot, luminous stars) to the lower right (cool, dim stars). This area contains about 90% of all stars, including our Sun. Stars on the main sequence are in a stable phase of hydrogen fusion in their cores. Other regions of the HR diagram, such as the giant and white dwarf areas, contain significantly fewer stars.
All stars.
The location on the Hertzsprung-Russell (HR) diagram where most stars lie is known as the main sequence. The HR diagram is a plot of stellar luminosity against surface temperature. The main sequence is a prominent band that extends diagonally across the HR diagram from high temperature and high luminosity to low temperature and low luminosity. The majority of stars, approximately 90% of all stars, are situated along the main sequence on the HR diagram. These stars are often referred to as main-sequence stars. They exhibit a smooth relationship between surface temperature and luminosity, with varying sizes and masses but sharing this common characteristic of lying on the diagonal band from the upper left to the lower right of the HR diagram.

Nebulae themselves are not directly plotted on the Hertzsprung-Russell (HR) diagram, which is a graphical representation of stars based on their luminosity and temperature. However, nebulae are often the regions where stars form, and the stars that emerge from these nebulae can be represented on the HR diagram. The HR diagram primarily focuses on the evolutionary stages of individual stars rather than the nebulae from which they originate.

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.
They are very hot stars.
