Hello,
You are enquiring as to whether you can get admission directly in 2nd year of B.Sc. Based on your Diploma in engineering? Right? Unfortunately, this lateral admission is possible only for engineering graduation and not for any other degree. Diploma is considered as equivalent to 12th and hence you are entitled for admission in first year only. Best wishes to you.

You will have to go through the prospectus of the course provided by the college to know more about the admission procedure, eligibility criteria, fees etc. It may vary eg DU has about 12k PA while VITS has around 1L PA.

Yes, you should be eligible for teaching 2nd-grade students, although it is much beneficial to become a professor in college. You can also try going to class 10th. All you have to do is apply for jobs in various private schools and try to clear the interview which is the selection procedure in most private schools. If you want a government school's job then you have to qualify exams like TET.
