Yes however I would use something corser like cement board or a wire lath and mortar scratch coat. You really need something for the stone to hold onto and such a smooth surface is not ideal.
I would not, Hardiebacker is a concrete product and therefore absorbs moisture.
This is the right product for the walls of a shower. I use mesh tape in the corners and then paint it with Red Guard. Watch a video on how you apply Red Guard. Most guys hold the backer board off the shower pan to prevent water wicking. The pan will hav a rubber liner poured with cement or be fiberglass. Don’t do a shower until you know how to get it right. They are a real pain to fix after the fact. Use a high quality grout and sealer on the tile. I often use drywall screws for spacers on the walls and it holds the tile in position pretty well against backer board. I let the tile dry for 24 hours before removing the screws and grouting. You can use a fan or space heater in n the bathroom to help cure the mortar if it’s cold or humid. Work a small area with the grout until you get used to it and wipe with a clean sponge. Clean the sponge after every wipe to avoid hazing. Let cure for 24 hours then seal. Don’t start until you are confident that you know what you are doing or you are going to have a big mess. Once you start you are committed. Don’t wander off before it’s finished or you will learn about pain at a whole new level.

Exterior use of HardieBacker depends on the climate you live within. Please refer to our Buying Guide under the Info & Guides section of this product page to learn more about using HardieBacker for exterior applications.
Yes you can it is made of cement and fibermesh to keep it together, it is flame resistant.
I would think that thinset and screws would prevent the backerboard from floating and could contribute to cracking. I've only ever screwed this down.
Sorry, it cannot be use in this application. It cannot be use in ground contact or any exterior floor applications.
Hardibacker is made for ceramic tile applied with thinset (mortar). There is no information on applying self adhesive tile. Hardiebacker is a rough, dusty cement surface. Self advesive materials need smoother surfaces. It would probably stick but it would probably come off very easily.
It is non-combustible but does not have a fire rating because it transfers heat too fast
