I have windows 8 and LibreOffice 4.2
LibreOffice comes with “some” fonts which are installed as the OS requires during installation of LibO.
Refer to this post.
All the fonts bundled with LibreOffice should be available under a compatible free license. The fonts you named seem not to belong to that category. Whatever font you want and have: install it into \Windows\Fonts with the proper means. You may have an executable that does it for you.
(The question is in principle a duplicate.)
