This is simply to make it easier. You can make self rising flour yourself. Simply do 1/2 tsp of salt and 1 tsp of baking powder in the bottom of each cup of flour.
Yes you can use self raising flour in a crumble.
White self rising flour can be used in any baking.
No. Self raising flour already has baking soda mixed into it (which is another leavening agent used in cake baking)
No, maida is not self-raising flour. Maida is a type of wheat flour that is finely milled and used in Indian cuisine to make various dishes like bread, pastries, and snacks. Self-raising flour, on the other hand, has baking powder added to it, which helps baked goods rise.
yes

corn starch
Not for making yeast bread. The baking powder and soda and salt in the self-raising flour will affect the yeast and probably kill it, resulting in a bad-tasting, dense mess. Self-raising flour can be used in quick-breads, that is the proper leavening for them.
Your cobbler topping will not rise at all if you do not use self-raising flour. This will result in a very hard topping. (Alternatively, add baking powder to the plain flour that you have used, which will give you "self-raising" flour. )
Either one will work, but plain is usually used.
No. Cornflour is made from corn and does not rise. It's used for different reasons than self raising flour which is wheat flour with bicarb already added. Be aware with cornflour that it can also be wheat flour if it says wheaten cornflour. That concept baffles me.
Self-rising flour is used to make breads, so it would be in the Breads/Grains/Cereal section of the Pyramid.
No. Rice flour is made from rice. Plain flour is refined wheat flour. Self rising flour is refined wheat flour with baking powder and salt already in it. Wheat flour has gluten, rice flour does not and cannot be used to substitute for wheat flour.
