Plain flour most likely is AP flour and I say yes at any rate.
No, the eggs are there to keep it all together after baking, milk will not do that for you.
The original Nestlés Toll House cookies (chocolate chip cookies) recipe calls for baking soda, not baking powder. There is no substitute for baking soda or baking powder in a recipe. You have to have it.

baking soda makes cookies bigger
No. Corn starch is usually used as a thickener (for gravies, soups, puddings, etc)., whereas baking soda is used as a puffer-upper for biscuits, cookies and unleavened breads and so on. Use flour as a substitute for corn starch, and baking powder as a substitute for baking soda.
I Can't Belive it's Not Butter! Seriously, it's not butter. Tastes, looks, and smells aren't everything. Thank you.
Baking cookies, baking cake, baking brownies or baking any in general
There is no substitute for baking soda.
It could be used depending on what you are baking. A better substitute would be Stevia.
You can substitute them - but it's really hard to get it right. Baking powder is soda - but with other things added. Baking soda reacts to acidic things (like buttermilk) because it's a base (slightly bitter.) Little hard to explain, but it's really easy. Baking powder is sort of in the middle. It has an acid and a base, and is very neutral. In a cookie recipe, baking soda is used. In a recipe, all the ingredients react together, so if you change one ingredient, you have to change others too, or the quantity. Swapping powder for soda will not get you the right cookies that are supposed to be made from the recipe. So you CAN substitute them, but it's just easier to go and buy some soda.
