Handoff question
 

NF. 7-3-1...Any player may hand the ball backward at any time.

7-3-2...No player may hand the forward except during a scrimmage down before a change of possession, provided both players are in or behind the neutral zone and it is to: a) A lineman who has clearly face his end line by moving both feet in a half-turn and is at least 1 yard behind his line when he receives the ball.

Since there are no exceptions listed in 7-3-1 is this to be interpreted that any player may hand the ball backward at any time ....to any other player?

Meaning does a lineman have to do the half-turn/face his end line thing in order to receive a backward handoff? Or can a lineman get a backward handoff any old way? Is there another rule that governs this?

The ball can be handed backward anytime, anywhere, with no restriction.

As long as you're understanding 'backward' correctly, backward handoffs are unrestricted.
