Bundelkhand Institute of Engineering and Technology

Yes, with this rank, you can get all the colleges you have listed above, even you can get HBTI too.

Yes, but you have less chances (around 75% chances) that you can get admission into those colleges at this rank, because lateral entry depends on the basis of vacant seats available in the second year.

Yes, you can admission in Bundelkhand University with this rank.

I think you should choose government UPTU colleges if you have a good rank and UPTU colleges should be IET, HBTI, CSJMU and Bundelkhand University. These colleges have very good placement records and these are top engineering colleges.

Yes, you can get IET and KNIT both, but not BIET.

If it's about placement then you can go for CSE, you can choose any of the colleges mentioned above. Anywhere CS/IT students get easy placements.
If it's about location. Lucknow is much better than Sultanpur in all aspects.
IET-Lucknow has a better campus than KNIT. Well, finally it all depends on your interest. As you already passed out 12th and if you're from CBSE board, you have already studied computer in last two years (I know it's option, but then also )
If you want to go for government jobs, just go for civil engineering, if you want to work in private sector, go for CSE.
