Plain, pasta dough is not supposed to rise.
No, self-rising flour cannot be converted back into all-purpose flour. Salt and a leavening agent, usually baking powder, are added to regular flour to make self-rising flour, and cannot be removed by any practical method.
There is no difference between plain flour and all-purpose flour. They are one and the same. All-purpose (plain) flour does not contain the salt and baking soda that self-rising flour has.
You can use self rising flour. Just omit any salt, baking soda, and baking powder. The texture is not as "heavy" and is the way I like it. Very tasty.
The store mix has to list the ingredients and be specific. Wheat flour instead of Oat, Rice, Buck Wheat or some other type. Plain flour means all purpose, not self rising, cake or bread flour. All purpose or plain flour being wheat flour.
Self raising flour has the salt and baking powder included. Plain flour does not.Self rising flour is a combination of flour, baking powder, and a little salt. It's not just flour.

If you were baking a cake: Self-Raising Flour - would make it rise Plain Flour - wouldn't make it rise People use self-raising in cakes to make them bigger, but they use plain in pancakes so it keeps it thin.
Follow the recipe for the amount of baking powder to use whether your using regular flour or cake flour. Neither of them have baking powder, unless it is "self rising" which means leavening is included.
Yes you can, I use whatever flour I have to hand.
