It's better to check the official website of DY Patil College. As a whole, it does accept JEE Mains Paper 2 score, but checking out the website is the best option.

There is a counselling process organised by JoSAA under MHRD directive. You need to appear for it. Select the desired colleges as the option and wait for admission dates. Before, that I'll suggest you should go for a few college predictors like Shiksha College Predictor app and research about the institution you get and then choose from there.

I'll simply suggest you should estimate probable colleges via Shiksha College Predictor app and research about the institutions that you like. After that go for the best-suited ones.

Yes, all the rankings are separate for JEE Mains and Advanced.

If you belong to general category, then chances of getting a good college is quite low and if you belong to any lower category, then you might have a chance.
I will recommend you to reappear the exam and try to score at least 230.
Best of luck.
