Lateral entry

No, with this rank for lateral entry, you'll not get any government college, but probably you can good private colleges like:
Galgotias University
BBD
SRGI
Ajay Kumar Garg Engineering College

On the basis of your SC rank, there is 70% chance that you can get IET Lucknow, but surely you can get seat in:KNIT.
BIET
MJPRU
KIET

There is only 50% chances that you can get any of the college you listed above because lateral entry depends on the basis of the vacant seats available in the second year.

Yes. For this you are to register for lateral entry admission online. Based on your mark if you are eligible (chances there if comes within top 10 in your stream in Maharashtra) you can get admission in second year of B.Tech in COEP. Best wishes.

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.

You have to crack the mit entrance exam MET. Please do check all the details written below
Eligibility for B.Tech Lateral Entry Admission under various categories is as under:
B.Tech Lateral Entry Admission under General Category: Admissions are offered based on rank in the All India Manipal Entrance

Yes, you can get but your 12th should be completed and also, you have to crack the entrance exam which is conducted by the state government.

No, after BCA, you can take admission in MCA first year, not in the 2nd year (lateral entry). If you are interested to take admission in the 1st year of MCA then you can take admission.

If you have your Diploma from an AICTE-approved college, then surely, you can have your B.Tech degree from Rajasthan through lateral entry in spite of you being from another state. Because AICTE is a central board.
