3/8 in. Compression x 1/2 in. FIP x 24 in. Braided Polymer Faucet Connector

yes, it will work for hat water.

I connected the large end to the new faucet and the little end to the new angle stop. There are no directional valves inside the tubes like a backflow preventer. So, yes, I assume you could swap the connecting points.

I turn mine until it was tight

I would refer to the manufacturer's web site for specific health and safety information.

No.

The difference is the jacket material. Both are quite tough, but the braided polymer is much more resistant to crimping when bent in a tight circle.

No. A garden hose uses a 3/4" connection.

I could find no time limit except that, on the product, the label states: "Do not reuse connector. Inspect annually. Replace if deterioration is detected or after 12 years." This implies, at least to me, that the product should last at least 12 years. More interesting to me, though, is the admonition not to reuse the product, so I'd have to believe that the warranty extends until the first time the product is removed or 12 years, whichever is shorter. Personally, I've never experienced or heard of a failure of this product when installed on clean machined parts without defective threads.

I would visit with a Home Depot Pro in the plumbing department for specific means to joint these two dissimilar metals.
