Shortening or lard could be substituted without any major change in the recipe.
yes it will curdle. High Ratio Shortening contains emulsifiers that allow it to hold a large amount of liquid without curdling. do NOT substitute regular shortening or butter into a recipe that specifically says High ratio or emulsified shortening.

Yes and yes.
No you cant

Yes you can. You can use any flavor you wish but sometimes you probably should just use the flavoring suggesting but it's totally up to you. That's what wee do when we make frosting for my cakes. I am a cake decorator and we substitute flavors depending on the flavor of the cake.
No. Lard is animal fat and shortening is vegetable oil that has been hydrogenated.
