The first, I expect requires no explanation!
The second and third are in the Bengali script, which is used primarily by Bengali and Assamese—but the letter ৰ is no longer used in Bengali.
The fourth is in the Devanagari script, which is used by many languages, but Hindi is the biggest one by far. (Second comes Marathi at about ¼ the native speakers, then Bhojpuri.)
The fifth is in the Telugu script which is primarily used by the Telugu language.
(Sources: personal knowledge of Bengali and Telugu and recognition of Devanagari, as an Australian who’s spent a lot of time in India, mostly in Telangana and West Bengal; and affirmation by Google Translate auto-detection of each one in turn, though that’s not very reliable as you’ll easily see if you try just pasting the whole lot in, and observe how it decides it’s Telugu, but still happily translates the others as “Merry Christmas”… except the Assamese, which it translates as “happy birthday”. Google Translate makes huge gaffes with Indic languages even if you identify the language correctly, and it just gets worse when it’s trying to translate it from a different language.)
