Helps them rise
Self raising flour is plain flour with a little baking soda in!
Self rising flour has baking powder in it so that is an ingredient you won't need to add. Self rising flour will help the scones rise and be light and fluffy.
To thicken the mixture and to help it rise.
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.

Self-raising flour Leavening agents are used with some flours,[9] especially those with significant gluten content, to produce lighter and softer baked products by embedding small gas bubbles. Self-rising (or self-raising) flour is sold premixed with chemical leavening agents. The added ingredients are evenly distributed throughout the flour which aids a consistent rise in baked goods. This flour is generally used for preparing scones, biscuits, muffins, etc. It was invented by Henry Jones and patented in 1845. Plain flour can be used to make a type of self-rising flour although the flour will be coarser. Self-rising flour is typically composed of the following ratio: 1 cup (110 g) flour 1 teaspoon (3 g) baking powder a pinch to ½ teaspoon (1 g or less) salt
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.

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.
Either one will work, but plain is usually used.
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. )
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.
