No, cornflour would not be a good substitute for wheat flour in cakes. The cornflour would produce a very different taste and texture than the whet flour, and the resulting cake probably would not look or taste as it should.
No, you cannot.
no, wheat bran is an additive that can be ADDED to products as where wheat flour IS the product
Not in all recipes; for most baking recipes substituting plain flour for cornflour will not work, since cornflour has no gluten (which is what makes dough springy) and it requires far more hydration. Adding some cornflour to the flour in baking will result in lighter baked goods, but only until the total flour is 5% cornflour; after that the baked good gets progressively more dense and inedible. Cornflour is useful for thickening custards, which plain flour is not so good at. But you cannot bake normally with cornflour. Both cornflour and wheat flour have a similar calorie content, wheatflour is lower in the glycemic load (GL) index compared to cornflour, and whereas cornflour is considered "highly inflammitory" (i.e likely to cause a reaction), wheatflour is only considered "inflammitory."
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.
You could simply use Almond flour or Wheat flour in place of the buckwheat flour.

I think so...
Flour, all-purpose (plain)substitute: Whole-wheat flour for half of the called-for all-purpose flour in baked goods Note: Whole-wheat pastry flour is less dense and works well in softer products like cakes and muffins. I,ve also heard of almond flour- something to look in to. Go to your local whole foods market, you can always find healthy stuff there

It shouldn't. It should only contain corn.
Whole wheat flour. However, in some recipes the results will be much heavier.
Absolutely. Cornstarch and cornflour are the same thing. Generally speaking, the product will be called cornstarch in the USA. In Commonwealth countries, except for Canada, it will be called cornflour. Cornflour may be made from either wheat or maize (it will generally be labelled as "wheaten cornflour" if it is from wheat). The word "corn" in this context goes back to Old English and meant "grain with the seed still in" rather than referring to a specific species. It is ground from the endosperm of the grain and has a "quick sand" appearance when mixed with liquid. It will yield easily to gentle pressure but will resist sudden or violent pressure. Cornflour corn starch is different from corn meal or polenta and these cannot be substituted.
