Cornstarch or Corn flour (for thickening): 1 tablespoon = 2 tablespoons all purpose flour or
1 tablespoon potato starch or rice starch or flour 1 tablespoon arrowroot 2 tablespoons quick-cooking (instant) tapioca For other uses such as the main flour it's rather tricky I think it's best to only substitute Corn flour if it's for thickening.

Yes but it won't be as good, most likely.

Flour and corn starch are measured the same, but the results aren't always the same.
yes if it is in a small amount
No. The corn starch is added to make a finer, lighter crumb, which cannot be achieved with flour alone.
I assume you mean corn flour. No, corn flour and rice flour have radically different textures, especially after being cooked. If this is not a concern then you might try it. *note: corn flour in the US is masa harina (powdered corn meal), whereas, in the UK corn flour is corn starch, actually a sugar rather than a grain flour.
Yes, you can. 2 tablespoons of all-purpose flour equals 1 tablespoon cornstarch.
A good substitute for corn flour if is being used for thickening, is potato starch. You can also use regular flour that has been mixed and cooked with a small amount of butter in a skillet beforehand.
There are some ingredients available that can be substituted for flour but the problem is that flour always works best. Corn starch is sometimes a substitute as is blanched almond flour. None works as well as flour.
Well, you could. But the end product would be quite different, without the crunch of corn flour (corn meal.)
It depends what you're using it for. If you're thickening gravy, corn starch works. For general cooking, you can use corn meal.
