yes, but a name, an alt_name and a nat_name are quite the same. I haven't yet encountered situations with more then 3 alternative names in the same language for the same thing, and that didn't fit into other kinds of distinctions either (short, official, old, ...). Are we maybe talking about different spelling (e.g. often coming from different transcription of non-latin scripts)?

IMHO more than 2-3 (alt_name and nat_name).
I've looked a bit around in taginfo and found an example for excessive indexed alt names: http://www.openstreetmap.org/relation/5725722
to me this looks as if the mappers wanted to work around some supposedly bad working search engine, looks more like SEO then like sensible tagging, but I might be wrong, I don't know the context.

if one of your sources "authorative", you could put the value under official_name, the other two could be name and alt_name (if there really isn't just a typo at least in one of them).

+1, I agree there might really be situations where this could be the best solution, but it is really, really rare, most of the cases where multiple values are actually used come from approximative mapping and would better be solved by more detail (e.g. area in area or node(s) in area rather than trying to put everything in one poor node).
