Confusion regarding EMNLP registration [D]

Hi, I posted some months ago and got some very helpful responses (for another conference), but I have some confusions regarding EMNLP (and the way registration works here).
To give some context, I used to work as an intern during my undergrads at an Indian uni (final year), and managed to write a paper as first-author and it got accepted to EMNLP Findings.
Now, post-graduation, I joined another university for my Masters, and when I applied for grant, they rejected, explicitly stating the lack of authors from the (new) institution.
I applied for grants from the older one, and still got rejected, as I am not a student any longer! (mentioned that they will pay for paper registration, however)
I would love to attend EMNLP (even if it is a findings paper) and can sponsor myself (travel, lodging, etc), however, paying for registration + author fees is too much for me. I have already applied for D&I (got rejected twice earlier) but pretty much exhausted all my options.

1. Do I have to pay separately for attending/presenting if one of the authors are already registering themselves?
2. If he registers himself, do I have to pay $350 student registration or less? I have ACL member registration.
3. What are my options (Is there any grants you know of?) I know Findings papers do not need to be presented, but considering it's a first author undergrad work which I am very proud of, I would love to be able to present the work there. I have managed to put together an emergency fund of a small amount of money enough for travel, lodging on the cheapest possible terms. Any help here is GREATLY appreciated! Thanks a lot!
