Can I claim the premium amount paid for them under 80D and if yes, please tell me what will be the maximum limit that I can claim?

For an individual Rs.15000 per year deduction is allowed under Sec 80D.

Please note that except from cash, any mode of payment is allowed as deduction like payment through cheque, debit card, credit card etc.
