Hey,
Currently, computer science and information technology branch students are having a huge scope.
In terms of placements, IITs (some) are the best options. Then we have NITs, BITS Pilani, BIT Mesra, etc.
You can check the respective websites of colleges to have a figural value of the placements section. Most colleges make them public.

You would most probably have to complete your M.Sc before you can enroll in a PhD program.

Different universities have different eligibility criteria for their Ph.D program. Please check with the university for admission requirements in their Ph.D program. On an average, the minimum requirement is 60% or 6.00-6.75 CGPA in their M.Sc. program. Please refer to the link mentioned below for a list of colleges which offer Ph.D programs and use the filters on the page to navigate to a program of your choice:

No, JEE is required only for engineering colleges across India.

Yes, a commerce student can opt for a beautician course. For vocational courses, I recommend you go only for reputed institutes in Ranchi, Jamshedpur or Kolkata.
