Yes, of course, you can apply for the M.Ed course, as you have completed your B.Ed already. So, you are eligible to take admission in any M.Ed colleges.
Best of luck.

Admission to KU via merit list counselling seems a challenge with 71% but don’t lose hope and try to enquire for management quota seats to KU from student helpdesk by either calling them or dropping a mail to their forum.

Yes you do b.com from JMI

Yes, admission is through counselling based on the rank/ score obtained in entrance exam conducted by TSCHE.

Both shifts are good, if you are a morning person then morning shift is preferred otherwise evening will be a better option.

BBA LLB from Amity University is better than B.Com. Since it's a professional course so you have better career options and will have a licence to practice law.

I do not think that with 46% marks you will be able to get admission in Delhi University.
