The simple answer is 50, although the total really depends on what counts as a language. The 50 incontestable ones break down as follows:
Additonally, the equivalent of 'Welcome!' in the language game, Pig Latin, is included, though this is scarecly a language.
Given that 'Welkom' means 'Welcome' in Dutch, Frisian, and Afrikaans, one could argue that the total should be increased by two. Similarly, both Czech and Slovak have the same word for 'Welcome', as do Serbian, Montenegran, Croatian, and Bosnian. We could continue down this path for many other languages in the song (the Indonesian phrase 'selamat datang' is the same in the language Malay, etc), so the total number of languages in the song could be argued to be well over one hundred.
Just in case you wondered, a song containing 51 languages is a far cry from a world record!
I submitted this song to Guinness, after Bryony Growdon (see Credits) suggested it, on the off-chance that it might have been a record, and this was their response:
Thank you for sending us the details of your recent record attempt for 'Song with the most languages in its lyric'. We are afraid to say that we are unable to accept this as a Guinness World Record.
This record category was previously monitored by Guinness World Records, however it has subsequently been rested owing to the impossibility of standardising what constitutes both a language and the use of a language in the context of songwriting. As such, we are no longer interested in listing a record for this activity. For your information, the record prior to this category being rested is 277, achieved by Sai 'Psychuck' Manapragada (India) and the crowd at the Festival of India in Fremont, California, USA, on 15 August 2010.
|#||Language||Spoken in||Native Script||Transliteration (Latin alphabet)||Approx Pronunciation||IPA|
Notes on the French:
Note the final vowel in /bjε̃•və•nʉː/. A Parisian pronunciation would be /bjε̃•və•nyː/ with the characteristically French /y/ at the end, but for the purposes of euphony in this song, please render the final vowel as /ʉ/ as in English. This will then rhyme with the word 'you' in the previous line. Singular (and feminine) is standard, as it is a ellipsis of "(Je vous souhaite/Nous vous souhaitons la) bienvenue" see: http://forum.wordreference.com/showthread.php?t=622040

|5)||Korean||North Korea||어서 오세요||oso oseyo||oh-so-say-yo||/o:.'so:.sei.'(j)o:/|
Notes on the Korean:
This literally means something mroe like "Welcome, please come in!", while 환영합니다 (hwangyong-hamnida) would have been more appropriate here as a translation of 'Welcome!' in this context, the temptation to marry 'oh-so-say-yo' with 'or so they say' in the lyric was irresistible! This poetic licence seems justified given the phrase "Be our guest and take a seat" that occurred a couple of lines earlier... We were already talking about 'inviting people in', so the Korean meaning is very similar!

Notes on the Indonesian:
Imagine the first 'e' isn't there. The 'a' is like 'u' in 'hut'
Notes on the Japanese:
The kanji is "歓迎"
|10)||Vietnamese||Vietnam||chào mừng||chow mung||/ʨɐ̤ːw˨˩ mɨ̤ŋ˨˩/|
Notes on the Vietnamese:
The vowel in 'mừng' is pronounced almost like the 'u' in 'put'
|13)||Hebrew||Israel||ברוכים הבאים||brukhim ha-baim||broo-kheem a-baa-yeem||/bɹʉ'xi:m aba'ji:m/|
Notes on the Cantonese:
The 'u' vowel is like the 'u' in English 'put'; the 'i' is pronounced just like the 'e' in English 'bed'

Notes on the Tamil:
This literally means "Come in!" in the spoken (informal) register of the Tamil language. Repeating such a greeting is common in Tamil, where saying it only once might even be interpreted as half-hearted!

Notes on the Croatian1:
Although the 'h' of spoken Croatian is harsh, like the Spanish 'j', when sung it's preferable to soften it so that it will sound like the English 'h'
|33)||Ancient Egyptian||Ancient Egypt||em hotep||em ho-tep||//|
Notes on the Latin:
Don't forget to say the 'v' as a 'w'! For the purposes of this song, the final 'e' of 'salvete' should be identical to the English 'ay' so as to rhyme with the word 'say' earlier in the same line, and with 'way' at the end of the next line, even though in Latin it would not have been a diphthong.
Notes on the Nepali:
The final vowel is like 'u' in English 'rum'

|48)||Inuktitut||Nunavut (Canadian Territory)||ᑐᙵᓱᒋᑦ||tunngasugitsi||toong-a-soo-git-see||//|
Notes on the Inuktitut:
The 'ng' should be as in 'sung', not as in 'linger' (but do 'linger' on the 'ng' a bit more than in English). I chose to divide up the syllables in this unorthodox manner - "toong-a-soog-its-ee" - in order to reinforce the fact that the syllable 'its' sounds the same as the word 'It’s' at the start of the setence. The plural form of "Welcome!" is actually ᑐᙵᓱᒋᑦᓯ (Tunngasugitsi), but I used the singular here to enhance the euphony of 'in' and 'it' with 'Inuit' and 'tunngasugit'. On forvo.com, the /u/ is silent.
