Answer 1

Let me give you a few pointers here:

1. You will be CHARGED for I/O data transfer 
2. You will be CHARGED even if it is transfer within buckets under the same account because it happens through the internet
3. Use this tool beforehand to calculate the prices - AWS Simple Monthly Calculator
4. Free tier is available in S3, so if you don't want to get charged, keep your requests within the below limit
