A red gyarados is a shiny gyarados (however, the Pokemon Company did not call them shiny untill the Unova Region). You can find it wherever you can find a normal gyarados, but your chances to find it are very slim.

Yes, but like on gold/silver/crystal versions you have to find them randonmly. there are no gift shiny Pokemon like the red gyarados
No, Gyarados and red Gyarados are basically the same having only one key difference; red Gyarados is a "shiny" Pokemon which changes its color and makes it rare to find in normal gameplay.
In Pokemon Silver you can find red gyarados in LAKE OF RAGE. You need to go up route 43 from Mahogany Citie = =
It Is a Shiny Gyardos if you want it red
you cant
you have to get lucky fishing or just trade in the GTS (online) and then breed the gyarados with a ditto.
Red Gyarados has no advantages over regular Gyarados. Red Gyarados is a shiny Pokemon, which has a different appearance but has identical stats to regular Gyarados.

the only way to get a red gyarados is to find one already shiny in the wild. you dont get it from someone in the game either.
