It is impossible to say when star constellations were "first discovered".The stars in the heavens have been recorded since man first learned to write.There are many instances of the stars being recorded in the Christian Bible and Holy books of other religions
Williamina Fleming discovered more than 10,000 stars, in which she discovered 59 gaseous nebulae, 310 variable stars and 10 novae.
You can't really talk about it as a discovery. People looked at the stars since times immemorial and named them. Why? Stars were pretty important for the navigation and it's surely easier to remember something if you can associate it with some object you are familiar with (cross for example).
I would imagine the first humans who walked the Earth. The planets Mercury, Venus, Mars, Jupiter and Saturn can all be seen with an unaided eye. They were, then, called Wandering Stars as they "seemed" to wander the skies unlike the "fixed" stars.
The red shift in stars was first discovered by astronomer Vesto Melvin Slipher in the early 20th century. He observed that the spectral lines of distant galaxies were shifted towards longer wavelengths, indicating that these galaxies were moving away from us.
No one discovered it, it was created. As to who created it, it is unknown. Maps of the skies and stars pre-date history.

Blue giant stars were not discovered by one person, as they have been observed and studied by astronomers over time. However, they were first classified and extensively studied by Annie Jump Cannon and Ejnar Hertzsprung in the early 20th century.
Population II stars are the oldest in our Milky Way. Population III stars were the first stars in the Universe, but have yet to be discovered. See related question
People in the beginning used the stars, and the seasons to keep track of time. So there is no one person that discovered time. The first time devices were the sundial, hourglass, and the water clock. In the 1300's is when the first mechanical clock was invented.

According to the Eclipse Aviation website, the most current number of stars that have been discovered by humans is around 100 billion stars just within the Milky Way Galaxy. There is also a catalog that compiles the images of over 84 million stars within the central parts of the Milky Way, which is currently the most detailed record of stars that have been officially confirmed as discovered.
