Yes, you are eligible for getting admission in MIT WPU Pune as your Diploma aggregate is good enough to get admission there. They will provide you the best knowledge and also the best placement. So you can try to get admission.
Good luck!!

I presume, yes. Any diploma holder is eligible for admission, provided he has the required rank in IPU-CET as the university takes entrance test for lateral entry as well.

No you are not eligible for the B.Tech. PCM subjects are included in the syllabus of B.Tech also but biology is the main subject for B.Tech but you can get admission in engineering.

Must have mathematics, physics and chemistry in 12th class and marks should be above 60%.
(Entrance exam or direct admission)

For doing B.Tech in any stream, you should have physics, chemistry and maths in your 12th class (min. 60% in +2 ). This is the basic criteria in almost all colleges.

You may sit in the placement process with your class 10th and graduation marks as your aggregate score would be in the 60s. However, there is a zero-day in the placement season when 13-14 companies come to campus which does not ask for any eligibility criteria. You can seize that day my friend.
