The color of a star does not directly determine its age. Red stars are large and a little less hot then the Sun. Scientists can use the color of a star to determine its heat and then using that and its mass determine how old it is.
From the material of old stars.
Not necessarily. Blue stars are short-lived compared to other stars, so they can never be very old, but a red dwarf star can be any age.
Yes, when stars get old and start to run out of fuel in their core, they expand and cool down, causing their outer layers to appear red. This phase is known as the red giant phase.
There are four red stars with five points each on the New Zealand flag, representing the Southern Cross constellation.
Red stars are not necessarily the oldest stars. Red stars are low-temperature stars that can be both old and young. The age of a star is determined by various factors, including its mass and chemical composition, rather than just its color.

Red giant stars.
new stars can get matter from old stars and comets really anything it can get its hands on
If they have red stars including giants in, they can't be all that featureless.

With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.

Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
It depends, as there are two general classes of red star. Red dwarfs are low-mass stars and smallest of all main sequence stars. Red giants and supergiants are old dying stars that are many times larger than other stars.
