There is no provision of admission in the second year for understudies seeking B.E. from other colleges. On the off chance that you are a Diploma holder, then it is conceivable. Hope it helps.
Thanks.

Use Shiksha's College Predictor Tool to know which college you can get on your UPSEE rank basis.

Yes, you can easily get it as my friend last year scored 5 lakh rank and easily got there in the first round of the counseling only plus there is first come first serve basis also so if you want there only then apply as soon as possible.

You have to score about 65% in the test in order to get the civil branch in first round of the counselling.

Mnit Jaipur is better then Chandigarh.

Yes, there is a good possibility that you might get into KNIT. You must try. You have got a good rank. There could be situation that you have to wait till the last phase of counselling.

Yes, but for that you have to clear all the FE subjects. That simply means, you have to pass in all the first year subjects.

One may find NITs attractive due to their NIT tag, but frankly speaking, all NITs don't stand up to that reputation. For people who have no or little idea about IIITs, I would like to tell them that the 4 IIITs (Allahabad, Jabalpur, Gwalior, Kancheepuram) are institutes of National Importance, just like any other NIT, and focus on the field of Information Technology exclusively (unlike NITs). Moreover, IIIT Jabalpur has an upper hand over the above NITs as it has a collaboration with universities of Japan. So I would suggest going with the following preference: IIIT Jabalpur, then NIT Jalandhar, then NIT Raipur.
