Yes, you can, you need to inform the 'someone' about the transfer and have a reason why you are transferring the money to someone.

The charge is around 25-50 rupees and it depends on amount, local, out-station, inward and outward factors.
Now we have the NEFT transfer wherein you can transfer upto 10 lakhs and the charges are Rs 25 + GST. You need just go to the SBI branch where the savings account is held, fill out a NEFT/RTGS transfer form. Have a cheque leaf with you. The name, account number, and the IFSC code of the destination bank.
You can do it online too, if you have the access. If you are transferring this money as a one off event either to you or someone else, please bear in mind that your CA/auditor will ask you the reason for this transfer while the IT return is being filed for this year.
