No, you cannot become a lawyer without a Law degree. You mandatorily need to obtain degrees such as BA/BCom/BSc/BBA LLB or LLB in order to be a lawyer in India. To become a lawyer, one must first complete three-year or five-year LLB from a recognised university and possess degree certificate. Then, they must enrol themselves in local Bar Council of the concerned state and enrolled as an advocate. Within two years of the enrolment, they must appear and clear AIBE in order to be eligible to practise anywhere in India. 

No, After completing LLB you become a lawyer, however, you are still not an advocate and hence cannot practice law. To become an advocate and to practice law as a profession, you mandatorily need to clear the All India Bar Examination (AIBE). After qualifying AIBE, one can practice law as a full fledged profession.
