For all Basic4Android standard libraries (located in the "libraries" folder), this is no problem. You can use it in commercial apps.
The using of additional libraries (located normally in the "additional libraries" folder) you downloaded from the forum belongs to the library authors. If you find no license information in the corresponding thread, it's best you ask the individual author.

Edit:
And even if the using of the library is completely free, it's always gracefully to mention the authors in a about box.
