You mean whether they are available as song/translation languages on LyricsTranslate? Some are (e.g. Klingon, Na'vi, Quenya and others). If you want to add a song/translation in a fictional language that's not available you can, just choose "Constructed Language" and specify what language it actually is in the submitter's comments. However please bear in mind that the language needs to have a well defined vocabulary, syntax and phonology (it has to be learnable by anyone who wants to).
