I am a salaried person with a getting 5lakh salary per year. I need home loan of 12lakhs. I need this loan within 3months. What will be my EMI and am I eligible for this Loan amount?

You seem eligible for this loan amount, but as you have not mentioned details of your other debts, I cannot confirm the eligibility. The EMI on a Rs. 12 lac loan for 15 years at 11% will be Rs. 13639.
