There is no length away you should be. As long as you dont touch the net you're good. I'm a setter that used to be a hitter and if anything the closer to the net you are, the better blocker you will be.
it doesnt matter as long as you dont touch the net :)
Volleyball
(Indoor Volleyball) 10 normal paces away from the net for varsity, if you're serving overhand, if you are serving underhand, you must be at lease 15+ paces away from the net when serving. Changes may apply depending on your gym size.

Depends...
you can be as close as you want to the net but you are not allowed to touch it. you're also not allowed to reach over the net to the over side of the court or put your foot over the centre line underneath the net
Well.... it scores the points, most of the time.
2 feet
because you need some space between the player and the net
90 degrees
it should be 30 feet but when you play u dont want to run into the pole so put them about 34 feet apart the net should be 30 feet
no part of your body can touch the volleyball net
