What is the gpf on this valve, thanks?

It varies per your own setting of your toilet (see those specs): You can turn the set screw all the way up for a more downward placement of the ballcock so that it fills the tank less. That way it may save a gallon of water or so, but may no longer flush forcefully enough as is sometimes desired. The better question would be to find a two-way push button for a lesser water need or more water need as nature calls for. ;-)

Will this work with the kohler san miguel k3402 toilet?

Some research indicates that you may want the #1068030 Kohler Toilet Fill Valve for the Rialto

I will this fit a Kohler Toilet model K3384 ?

It should.Check with kohler dealer!Best wishes!

What hose can I use for the the top spout? Is there a way to turn it off? My old one did not have water coming out the top.
