Yes, you can but college change or university change after first year is completely dependent on college and university norms, some university allow it and some won't plus you need to have good scores in first year to apply for the same. For further details contact the college authorities.

You won’t be able to get admission in a good B.Tech college only on the basis of 12th percentage. I would recommend you to go for national and state level entrance exams like JEE, BITSAT, MHTCET, etc.

1- GATE syllabus is same as that of engineering subjects.
2- Revise all the core subjects.
3- You may join coaching depending on your grip to the subjects.
4- Start solving questions from a good book for GATE and get started with the pattern.

B.Tech will be more technical in nature whereas B.Sc will be more scientific. You will get exposure to practical use of the subjects in B.Tech.

Hello Udhaya,
You can opt for Jeppiar Engineering College as it will be better than the other colleges.
After that you may choose, Chennai Institute of Technology.
The rest are not that good as compared to CIT and Jeppiar.

In order to pursue B.Tech CS you need to have maths as a compulsory subject along with physics and chemistry. There is no harm if you have biology but this is very harmful if you don’t have maths. However, you can do B.Tech in biotechnology or some related course but not CS.
