Question: These are the standarad icons I am referring to.

Are these able to be used in apps that are for sale. I am assuming not. But it would save some time if I could use any.

Answer: 
These icons are available in the sdk (`platforms\android-XX\data\res\drawable-[whatever]`), so I would think they could be used in your commercial app. When you use these, you can access them via `android.R.drawable`, but it is better practice to copy the files and include them in your project for consistency.
There are many icons on the [official Android Developer resource](http://developer.android.com/design/downloads/index.html)
