It wouldn't get softer or harder. It would get yuckier.
Alloys are harder than the components.
No, whipped cream is heavy cream and sugar that is whipped at high speed until the cream is stiff. If it were whipped further the cream would turn into butter. Ice cream is cream, milk, sugar and flavorings that are churned slowly for up to an hour and then frozen.
It would ask for cream and sugar.
If you put in too much sugar, the ice won't freeze properly, since sugar lowers the freezing temperature.

Most likely you would be testing to see if the mineral was harder or softer than the nail.
Generally whipped cream would be healthier -It's a lot of fluffed air, while ice cream is full of fat.
Sugar acts as an "antifreeze" in ice cream to suppress the growth of large ice crystals. Without sugar the texture of ice cream would not be smooth and creamy, instead it would be "gritty" due to the large ice crystals. Ice cream without sugar can also become hard and unscoopable during extended storage in the freezer. There are sugar free ice cream recipes that substitute other ingredients that have similar "antifreeze" properties to sugar but without the carbohydrates/calories, but these substitutes must be carefully selected to avoid altering the flavor too much.
I believe that the sugar makes the dough softer. The recipes I have seen do not seem to include large amounts of sugar, so amending the amount would just change the texture rather than taste.
I would say a classic butter cream.
Although it's normally made from heavy cream, whipped topping includes sugar (and possibly vanilla) when heavy cream doesn't. At least all whipped cream recipes I've looked at call for sugar. Plus air is incorporated and I don't know what effect using as a sub for heavy cream would have. Anyway, I would say no, not really.
it may or may not freeze faster, but the sugar acts as an antifreeze to suppress the growth of large ice crystals giving the ice cream a creamer texture.
