1.In a PPF account you can invest within a range from 500-70,000 Rupees in one financial year.
2. Yes you can open PPF account for all the earning member of house, but now a days it is not advisable to do so. Its better to go FD in national or private bank where u will get an interest rate of about 9%, whereas in PPF its 8% and if you are going for 5Yrs FD then you will get TAX benefit under the same section as well. In PPF locking period is high 15 Yrs.
