Teacher

Yes but I think you have to clear NET exam that is National Eligibility Text to become a government appointed teacher or lecturer.

You may not be deemed eligible to work as a nursing tutor. The minimum eligibility to teach even GNM is B.Sc in Nursing.

For Ph.D, you need to clear UGC NET. As soon as you clear it, you will be deemed eligible to do Ph.D.

Yes, you can teach in schools by giving CTET entrance exam, provided that you have some degree or Diploma in education field. Then only you can apply. If you don't have B.Ed degree or any Diploma in education then do it in order to teach in a good government school with a good salary.

As per my knowledge and my opinion, to become a professor in Government University, you can go in any of the two options, you have mentioned, as if you go for B.Tech M.Tech and then Ph.D. You are eligible for professor in University of Technology, and if you go for B.Sc M.Sc and Ph.D, then you are eligible as the subject teacher of the respective subject in which you have completed the graduation post-graduation and Ph.D.

As per my opinion and my knowledge for doing Ph.D from New Delhi, you must have to give an IIT exam and have to qualify it, so that you can get enrolled yourself in Delhi University for Ph.D in Jamia University in New Delhi, but all these universities, you must have cleared the NET exam. For a professor, you must have to complete your Ph.D degree first, and then you are eligible for a professor in any university.

As per my opinion and my knowledge for applying for the post professor lecturer without completing Ph.D after qualifying UGC NET, you are not eligible as their rules have been changed after 2016, as you must have a Ph.D degree 4 and lecturer, but yes you can apply for assistant professor, if you enroll yourself for Ph.D. and have qualified your UGC NET.
