A gold geodude is just a shiny geodude you must keep finding geodude in granite cave until its shiny.
You can find a Geodude in just about any cave or certain patches of grass. Also breaking rocks using rock smash has a chance of encountering a Geodude.
A red Geodude isn't in any of the Pokemon games, unless it was imported into a ROM hack.
Anywhere you can find geodudes, but they are extremily rare.

You can find one in granite cave.
What you have encountered is a shiny Geodude, which, as you described, is gold and a normal Geodude is a light gray color. Think of shiny Geodude as a gold nugget and a normal Geodude has a regular rock.
Geodude will evolve into Graveler.
No, Geodude is not a real creature. Geodude is a fictional character only in the Pokemon franchise.
