Powdered sugar has a buffering agent in it that keeps it fluffy and prevents lumps. This means that powdered sugar has a finer texture but doesn't work well in clear drinks, as they won't remain clear, even when the sugar dissolves. Superfine sugar is pure sugar, intended to dissolve easily. It does however have a slightly crunchier texture. So, if you don't mind the texture change, you can substitute superfine when the recipe calls for powedered sugar, but not the other way around.
Yes, you can use caster sugar instead of granulated sugar. However, be careful on the measurements. Use a little less caster sugar. Caster sugar is finer granulated sugar.
