I am trying to connect to RDS Database from an AWS Lambda (Java).

Which IP should I enable from the RDS Security group rules?

You can't enable this via IP. First you will need to enable VPC access for the Lambda function, during which you will assign it a Security Group. Then, within the Security Group assigned to the RDS instance you will enable access for the Security Group assigned to the Lambda function.
