Hello Jaswinder,
You have managed to score very well in your boards and JEE Mains. So, you should go for B.Tech only. However, considering your score, you will easily get colleges like LNMIIT, NMIT, Thapar Univ. and JIIT-Noida. You may also get lower NITs in the last phase of counselling. Check here

I can't predict the rank but with this score, your son will get metallurgy or production in the College of Engineering-Pune. Analyzing previous years records, I answered your question.

Following are the good options for you:
Bharati Vidyapeeth
Rizvi College of Engineering
St. Xavier's Institute
Dr. Babasaheb Ambedkar University

You must go for computer science and engineering because the placement in DTU for computer science and engineering is very good and you may get a lot of opportunities in this branch.
Thank you.

Yes, you can pursue chemical engineering from Institute of Chemical Technology, Laxmi Narayan Institute of Technology or Maharashtra Institute of Technology.

You should opt for B.Tech in CSE.

DTU has one of the best placement record after legacy IITs. If you study well, you will definitely get placed in a good company.
