You can do this using AWS Identity and Access Management (IAM). You can use this to create multiple identities and assign various permissions to those identities.

Here's a relevant example taken from the Amazon docs:

Example 1: Allow each user to have a home directory in Amazon S3

In this example, we create a policy that we'll attach to the user named Bob. The policy gives Bob access to the following home directory in Amazon S3: my_corporate_bucket/home/bob. Bob is allowed to access only the specific Amazon S3 actions shown in the policy, and only with the objects in his home directory.

{
   "Statement":[{
      "Effect":"Allow",
      "Action":["s3:PutObject","s3:GetObject","s3:GetObjectVersion",
      "s3:DeleteObject","s3:DeleteObjectVersion"],
      "Resource":"arn:aws:s3:::my_corporate_bucket/home/bob/*"
   }
   ]
}
