Hi Komal!
Yes, of course, you can pursue the certificate course in radio jockeying from the University of Mumbai. It is a part-time course of 4-week duration. You can download its brochure from here https://www.shiksha.com/mass-communication-media/radio/course/certificate-course-in-radio-jockeying-university-of-mumbai-fort-13947

Yes, you can do Masters in hr after completing graduation. Though MBA is not mandatory for it but doing a MBA will increase your opportunities.

Well for M.Sc Degree at IIT Bombay, you need to give IIT JAM exam. I have given GATE exam (not JAM) for M.Tech, but my guess is that the admission procedure would be similar. Get a rank within top 150, after which are shortlisted for screening test+interview (sometimes only interview). Only after clearing those interview you are admitted. For an IITian the GATE/JAM exam is exempted but you need to clear a minimum GPA limit for this. And yes, maths is compulsory.
