Rigel's effective temperature is 12100 K. 8 million Rigels would not be 8 million times at hot. In fact, in all likelihood the super-Rigel could well have become a super-massive black hole and be incapable of radiating at any temperature..

Is Rigel a young star?
Compared to the sun, yes. It is only around 8 million years old.
Who discovered Rigel?
Rigel has been visible in the night sky for over 8 million years. It would have been seen by the first creatures who looked up into the night sky. So no one can be said to have discovered Rigel.
How old is the star Rigel?
Rigel is a B8 class star which means it is very large, very hot and very young by comparison to other stars. It is virtualy impossible to age a specific star. This is usually done by aging star clusters, a much more accurate method. Rigel is estimated as being 17 times as heavy as the sun and through a standard formula should have a main sequence lifetime of 8 million years (very short) which means it is less than 8 million years old. It wasn't there when the dinosaurs were there. The formula is (mass of earth / mass of other sun)^2.5 * 10 Billion years The formula isn't perfect - there are other factors but this is a good guess.
What is Rigel's life cycle?
Rigel, or to be more precise, Rigel-A is a blue white super giant which started life with around 24 solar masses. , over a period of around 8 million years it has exhausted its hydrogen and has moved into the blue super-giant zone of the H-R diagram. It is expected to end its life as a type II supernova.
What are 8 conspicuous stars of magnitude 1 or brighter?
Our Sun is the brightest star of course, but presuming you discount that, the next brightest are:Sirius, Canopus, Alpha Centauri, Arcturus, Vega, Capella, Rigel and Procyon.https://en.wikipedia.org/wiki/List_of_brightest_stars

Is the star rigel an infant?
It is young - only 8 million years old compared to our sun's 14.5 billion years. However, it has already burnt up all its hydrogen and has expanded to a blue-white super-giant. It is a short lived star which will end its life as a type II supernova.
