I had only heard about six of these languages before. It's good to know that there are more languages.
I am guessing there are probably 6 million L1 Hebrew speakers rather than 5 million. Here is how: in Israel there are approx. 6.5m Jews, out of which probably 1m are first-gen olim, which translates into 5.5m native speakers ... add here those non-Jewish Israelis, who happened to have learned ivrit as L1, and a few hundred thousands Israelis living abroad = 6m.
