Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
Let's imagine the following objects first: Sugar cubes are solid blocks, each with a comparatively larger volume. Granulated sugar is fine and particulate, and each grain has a very small volume. It is only logical that when comparing one block of sugar to one grain of sugar, that the grain dissolves faster because it has a smaller volume (less to dissolve), and the surface area to volume ratio is much higher.
it will dissolve into water and if you put it on paper it will dissolve in air
depends!
If the initial temperature of the lemonade is equal for both the water and the ice then the cubes would cool lemonade faster because they have a lower initial temperature.
Sugar has very little effect on melting point - it is too high molecular weight. That might answer your question, which does not make sense as written. Thus, it melts faster with sugar, because other ice cubes slow melting.
I never heard of crushed water. Crushed ice (which sugar cubes don't dissolve in at all), but not crushed water. Let's see here: sugar dissolves faster in hot water than cold. And crushed sugar cubes, because the sugar has more surface area, dissolve faster than cold ones.
A sugar cube will - one, sugar cubes are designed specifically to dissolve quickly into solvents such as tea, coffee, liquids to make solutions. Granulated sugar, on the other hand, is often a solute for solid solvents such as flour etc. However, the granulated sugar can be dissolved more quickly if stirred, which makes the solute particles attract to the solvent particles more efficiently.

Hot water
sugar cubes
sugar cubes dissolve faster than limestone
water!
Ice melts because of heat, coffee dissovles because of the hot water
My experience is the finer the grain, the quicker it dessolves. Make some scientific sense too as, to dissolve, it must be broken down. So if the solute (sugar) is already partially broken down mechanically, there's less "work" for the solvent (the liquid you are dissolving it into) in creating the solution. So, powered sugar.
Assuming that bottled water is purer than tap water, has less ions etc, and that both volumes are the same, then sugar cubes would dissolve faster in bottled water. Thermodynamically there is less entropy in tap water than there is in purer water, so hydrogen bonding with sugar (which is polar) would be more favoured in bottled water.
She put two sugar cubes and cream in her coffee.
