Yes yes you can... You can use premade or the one you roll out but make sure its wont turn into a flaky crust because that night not taste right. :)
Yes you can use a kuchen crust for any pie.
You will use a pre-baked pie crust when you are making a cream pie, when filling the pie crust with fresh fruit, or anything that does not require baking.
A blind baked crust
You can, but it may result in the crust not being quite as flaky as it would be if you use an all purpose flour. Just be sure to not add any salt to it since self-rising flour already has salt in it.
Because of its composition. Flaky crust uses steam (created from the fats used) for rising and texture, where doughs use yeast for rise, and less fat.

Sweet potato pie is usually made with a regular single pie crust made with flour, lard / shortening, a bit of salt and cold water. The crust should not be pre-baked. Also, a graham-cracker pie crust is quite tasty with sweet potato pie.

It must first be blind baked
Well, they are nominally used to keep the bottom crust flat during the crust baking, preceding the actual pie bake.
A single pie crust is a crust that will fill the bottom of the pie tin - or cover the pie on top - but not both. A double pie crust requires about twice as much dough, and is enough to cover both the bottom and the top.Some pies, like pumpkin, typically have only a bottom crust. Others, like apple pie and meat pies, use both a bottom and a top crust. The top crust functions like a lid on the pie, helping to contain the heat while the contents bake.
