You should add Sumatra PDF that is a free software and that render PDF with a very good quality (it uses muPDF). If a part of sumatraPDF uses rar, you can simply mention it.
In order for a piece of software to qualify as "free", all of its dependencies distributed alongside with the software and all of its non-optional dependencies must be free. unrar in SumatraPDF does not qualify as such, however.
On a brighter note we do intend to re-add SumatraPDF once they have pushed out the next stable release as unrar has been removed from the development source tree and we are not aware of any other non-free software in the source tree.
Sincerely yours,
