For CSE, Galgotias University would be a better option.

Yes, many colleges give admission on the basis of merit and Galgotias University is one of them.

In my opinion, CGC-Landran is a better option in terms of placement and college environment.

Yes, you can get Sharda Univeristy, Galgotias University, and Or GNIOT College.

It is upon you which university you want to get in.
In Delhi, many universities provide BJMC.
Few of them are:
Amity University
IPU
DU
Some other private universities too.
I have no idea about Lucknow.
