Font malayalam.ttf is under GPL, from 
http://malayalamlinux.sourceforge.net/downloads/downloads.html#fonts

Font raghu.ttf is freely distributable, from
http://rohini.ncst.ernet.in/indix/download/

The font mdk_teams.otf is under X licence; it is based on the "Teams"
font, which has only basic ascii and basic russian cyrillic; and
I (pablo@mandrakesoft.com) added several latin and cyrillic glyphs
to cover all languages not covered by latin1 fonts, so that all
cyrillic and latin languages could use Xft and antialiasing with scalable
fonts out of the box.
The added glyphs are not always very nice, you are welcome to improve them.
