no.
Yes you can but you may be comrpromising flavour depending on what your are making.

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. It is not as fine as powdered sugar, but it is in between granulated and powder. Caster sugar dissolves more easily,so it is very beneficial in making meringues.
Anything that is not pre-packaged is considered to be homemade in cooking. Homemade soup is made with fresh vegetables instead of canned.
Granulated zinc is used instead of a block as the surface area of granulated zinc is much more than that of a block. Hence it's easier for it to react with oxygen if the area is more. This is why it's used.
