"O Mio Babbino Caro" is sung in Italian, and the pronunciation can be approximated as: "Oh mee-oh bahb-bee-noh kah-roh." Each syllable should be clearly articulated, with a soft "b" in "babbino" and a rolled "r" in "caro." The melody also affects the delivery, so it's important to maintain the lyrical flow while singing.
Very Annie Mary starring rachel Griffiths and Ioan Gruffudd
Originally sung in German
The aria is called "O mio babbino caro" (Oh my dear papa), which is from the opera Gianni Schicchi, by Giacomo Puccini. Most famously (in my opinion) sung by Maria Callas.

I can only assume you mean the song that was sung by Andrea Bocelli. As you can tell by her surname the song is in Italian.
I'm pretty sure opera can be sung in any language, but most times its sung in Italian French or German
Punjabi is the language that most bhangra music is sung in. How it is sung would depend on the particular song, whether it is fast or a slower song.
