Flags for Indian languages
Since there are a number of Indian languages that are being developed on Duolingo right now, such as English for Tamil speakers, English for Telugu speakers, English for Bengali speakers, English for Punjabi speakers, and Hindi for English speakers. I understand that Duolingo will use the flag of Bangladesh for the English course for Bengali speakers, but what will be used for the remaining Indian languages? Hindi already uses the Indian flag, so I was wondering if Duolingo would repeat this flag for other Indian languages as well (given that there are reverse courses for English speakers). Indian states do not have flags, so this wouldn't be an option.

Very likely "no", IMO, as it would defeat the purpose of identifying each course at glance (even for the courses teaching English from them but even more for courses (not only for English speakers) teaching those languages that will appear on Duo in the future).
but what will be used for the remaining Indian languages?
AFAIK, even staff doesn't know yet (which is the main reason why the “flags" are "eggs" at the moment). They still haven't decided.

That's what I was thinking, but I saw that the English for Punjabi speakers also uses the Indian flag, like Hindi.
I wouldn't draw too many conclusions from the Punjabi flag as it's a remnant from the old, old website i.e. from late 2013 - early 2014. I don't just mean the decision was made back then, I mean the file itself pre-dates the existence of flag sprites and is the only one still located in the incubator itself. I think if they were to use the Indian flag, they would have already updated it to the one on the sprite.
Duolingo has so far shown a tendency to make the flags as clear as possible. They're even not using the Mexican flag for Spanish, when that is the variety of Spanish being taught, solely because of the potential mix-up with the Italian flag (compare with USA flag for English). Thus, I'd assume that using the same flag for multiple courses would be highly unlikely and by far the last resort. They'll probably try to use regional or unofficial flags of some sort, but which ones, I couldn't say. (Maybe they'll use the Singapore flag for Tamil since its the only one of the three countries of official status that is relatively "free"? Seems far-fetched tho.) Only time will tell I guess.
It indeed isn't but this is my logic on why it's a possibility:
Tamil is an official language in three countries: Sri Lanka, India and Singapore.
Out of those, India has been taken by Hindi and Sinhalese would make much more sense (considerably more speakers) for Sri Lanka. So Singapore is the only one left of those.
Singapore's official languages are Mandarin, Malay, English and Tamil. The other three have been or can be semi-easily distributed to other flags. So Tamil is the only one left.
So yea, clearly suuuper far-fetched, but at least that's better than using a non-recognized or made-up flag? Maybe, possibly?
Duolingo has been lazy lately regarding to flags, High Valyrian could have a made up flag design from its creator, Haitian Creole should already have the Haitian flag, Yiddish has been in the incubator for ages and doesn't have a flag yet even though a possible design has been in the incubator files for ages too.
