I prefer two, to be honest.  I don't usually use it though because my teachers will flip out if I do.

1)  No.  Between every sentence, not every word.

Like this.  I would leave two spaces between a sentence for spacing preference.  See how it separates the sentences more and better establishes a flow of thought.

(Out of personal observation, I've noticed that starting from my childhood, people seemed to type more with one space.  I've also noticed that people began reading sentences as if the whole statement were one large stream of words.)

Holy stuff that is ugly and has zero flow. I want to puke just looking at it.

One, like normal people.

one because i type decently fast and tapping space twice is a waste of time

I use 1, but in school teachers make you sometimes do 2 because they have room to grade and make corrections.
