All constellations are imaginary diagrams formed by patterns of many stars - each one it's own unique distance from Earth. So a constellation isn't a particular distance from Earth - as the stars only look like they're next to each other from our perspective here on Earth.
8 billion light-years.
The closest red giant to Earth is a star named Gacrux (also called Gamma Crucis). It is 88 light years away from us and can be seen in the constellation of the Southern Cross.
Northern or Southern edges of the earth far away from the equator.
I think the name gives the game away! Southern hemisphere However it can be seen as far North as +20o
The constellation Norma is approximately 200 million light years away from Earth. It is a small and inconspicuous constellation that can be seen in the southern hemisphere.

The Southern Cross is not an actual object. The constellations are ways of grouping stars in ways that make sense to earth observers. The stars of this constellation may or may not be in reasonable proximity to one another, but in any event, you would have to consider the distances of each individual star. See link for more. Three of the four stars in the Southern Cross are at approximately the same distance. They are the two brightest ones and the faintest one, which are between 600 and 680 light years away. The other one is at about one fifth the distance, 135 light years.
About 25 million miles away from earth.
