is this fit to mazda6 3.7L v6 2012 ?

Bosch 6728 is the correct spark plug for a 2012 Mazda 6 3.7l v6.

Will these plugs work in a 1984 chevy g20 full size van with a 350 motor?

no use 6712. 6728 are not correct

What is the gap on this ?

I don't know if this helps you, I use it for my Ford f150 pick up and it works great.
