Because stars temperatures range from 11,000* Fahrenheit to 27,000,000* Fahrenheit depending on what part of the sun you are talking about. This is unsuitable for life as we know it to exist.
To give the number 11,000* some more understanding, that is around 5 times hotter than most kinds of lava/magma (rock so hot it is in liquid form) on earth.
Young stars are newly formed stars, often bright and hot, that are still in the early stages of their life cycle. Old stars are stars that have aged and passed the main sequence phase, becoming cooler and larger. Dead stars refer to objects that were once stars but have reached the end of their life cycle, such as white dwarfs, neutron stars, or black holes.
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
Most stars in the universe are main sequence stars. These stars are in a stable phase of their life cycle where they generate energy through nuclear fusion in their cores. The Sun is a main sequence star.
The life span of a star is determined by its mass. More massive stars burn through their fuel faster and have shorter life spans, while less massive stars have longer life spans. The life span of a star can be estimated using the mass-luminosity relation and the star's initial mass.
I am not aware of any specific element "signaling" this. Towards the end of a stars life, however, relatively large amounts of heavier elements are produced.
No; stars are not, to the best of our knowledge, "alive".
No, but some stars end their life by becoming a black hole.
stars live for about ten billionyears
Stars are suns and cannot sustain life. Earth is well, earth, and it CAN sustain life.
The massive stars turn into gas
Suns
10 billion years or less if stars collide
Nothing that we know of can survive the heat generated on surface of stars, therefore, no. Planets could carry life forms.
No, stars are not habitable for life as we know it. Stars are massive balls of gas undergoing nuclear fusion, producing high temperatures and radiation that are inhospitable to life. Planets orbiting stars can be habitable depending on their distance from the star and other factors.

Yes, iron is present in stars. Iron is formed in the cores of stars through nuclear fusion processes and is an important element in the life cycle of stars. When a star reaches the end of its life and goes supernova, iron is released into space, where it can be recycled into new stars and planets.
