Because it is so large. Density is a function of mass/volume.
The density of Betelgeuse is extremely low: 1,119.10 ex.-8 from the density of the sun.
Betelgeuse has a density of about 1.119 × 10−8 that of our Sun. See related question
Betelgeuse is so luminous because it is so large.
Betelgeuse is about 1,180 times larger the Sun. So Betelgeuse is about 128,620 times bigger than Earth. So as a rough approximation about 2,127,774,087,928,000 Earths could fit into Betelgeuse. That's 2 quadrillion.
Yes: Betelgeuse is a semiregular variable star so it is classed as a pulsating star.

if it is high the density is high so if the temperature is low the density is low.
Yes, hydrogen can be considered to have a low density. In fact, it is the least dense of all the elements.

The Indus Delta has a low density of population due to factors such as frequent flooding, high salinity in the soil and water, limited fresh water availability, and lack of infrastructure and economic opportunities. These conditions make it difficult for people to live and work in the delta region, resulting in a sparse population compared to other areas.
Jammu and Kashmir is a state in India; the population density is not so low for a region in the mountains - 56/km2.
Betelgeuse is a star, so there is little chance that anyone lives on it.
Yes: Betelgeuse is a semiregular variable star so it is classed as a pulsating star.
Low Density a Metal?NO!!!!
Saturn has a very low density and it would be able to float on water. The density of Saturn is: 0.687 grams per cubic centimeter.
