Hello.

S3 bucket names must be publicly unique, so if the bucket name "ronaldo001" is used in another AWS account, you will need to use a different bucket name.
https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html

A bucket name cannot be used by another AWS account in the same partition until the bucket is deleted.

If changing the bucket name to something else does not resolve the error, could you please copy and paste the exact error message and share it with me?

    By the way, in the following part of the CFn template, the bucket name is obtained with "!Ref S3Bucket", but with this, the name "ronaldo001" is set, so you need to set another random bucket name.

      DevFolder: 
    Type: 'AWS::S3::Bucket' 
    Properties: 
      BucketName: !Ref S3Bucket 
      Tags: 
        - Key: 'Folder' 
          Value: 'dev/'

  DevMgsAllReadonlyPdf: 
    Type: 'AWS::S3::Bucket' 
    Properties: 
      BucketName: !Ref S3Bucket 
      Tags: 
        - Key: 'File' 
          Value: 'dev/myreport.pdf'

    Give each S3 bucket a different bucket name. "mrinal009" may only be used once. In other words, use a different name for each bucket, as shown below.

      S3Bucket: 
  Type: 'AWS::S3::Bucket' 
  Properties: 
    BucketName: 'ronaldo001' # Replace with your bucket name 
    VersioningConfiguration: 
      Status: Enabled 
      Tags: 
        - Key: 'Name' 
          Value: 'ronaldo001' # Replace with your bucket name tag

  DevFolder: 
    Type: 'AWS::S3::Bucket' 
    Properties: 
      BucketName: mrinal009 
      Tags: 
        - Key: 'Folder' 
          Value: 'dev/'

  DevMgsAllReadonlyPdf: 
    Type: 'AWS::S3::Bucket' 
    Properties: 
      BucketName: mrinal010 
      Tags: 
        - Key: 'File' 
          Value: 'dev/myreport.pdf'
