I am wondering if a Gyroscope if built as tall as Mount Everest and also is able to be spun like a small Gyroscope can, will it function the same as a small Gyroscope will it balance in the air like  a Gyroscope? What happens if you keep building it bigger and bigger?

It depends what you mean by possible. 

A gyroscope that large would, of course, work like a gyroscope. But you couldn’t build one because there isn’t a material strong enough to stop it collapsing under its own weight. 

Pulsars are big, very heavy, and act like gyroscopes.

There's a very large gyroscope conveniently to hand. Wait around a few tens of thousands of years and you'll see it precess. Locals call it 'the earth.'

I wish I had thought of that!
