It will lower the softness sufficiently. You wouldn't want 100% soft water, you won't like the taste or the amount of sodium in it.
It is salt, sodium chloride, which softeners use to strip the cation exchange resin beads of calcium and magnesium, (hardness), to regenerate them. So you should be able to use it, but at $0.83 per pound it's much more expensive than the $0.09 per pound softener salt.
You can, if the water presently in the pool is 'hard' - but be very careful to keep an eye on the Calcium Hardness of the pool water. If you filled a pool with water from the softener, the water would be hungry for calcium and drag it out of the pool walls, making them feel and look like sandpaper. Calcium hardness should be kept within 200-275ppm. best to use regular water for topup and keep the pool water properly balanced (see your local pool store).
The reason you choose a water softener will best allow you to chose a saltless softener or a traditional softener. If you are using a water softener to help your household plumbing stay clean and gunk-free, then you should choose a traditional softener. If your goal is to have softer feeling and tasting water then a saltless softener will work just fine for you. With this softener, you are not actually removing salt, just changing the electric charge of the water.

Not necessarily, but it should not harm them. Downy fabric softener was tested at the University of Wisconsin, and found to stunt the growth of plants, however Downy is not an "ecologic" or "green" softener.
It should not be a problem at all. A: you should not have a water softener tied into the swimming pool PERIOD. The product resulting from a water softener can be detrimental ( not good) to the pool plaster and the equipment. In fact, it may harm the salt system readings and components.
