Answer 1

I tried rewriting your second template with the import function. Can you try something like this:
AWSTemplateFormatVersion: '2010-09-09'
Description: This template will create an s3bucket
Resources:
S3Bucket:
Type: AWS::S3::Bucket
Properties:
AccessControl: PublicRead
BucketName: CodeDeploy
CodeDeployApplication:
Type: "AWS::CodeDeploy::Application"
Properties:
ComputePlatform: ec2
DeploymentGroup:
Type: AWS::CodeDeploy::DeploymentGroup
Properties:
ApplicationName: !Ref CodeDeployApplication
Deployment:
Description: First time
IgnoreApplicationStopFailures: true
Revision:
RevisionType: S3
S3Location: !Ref S3Bucket
ServiceRoleArn:
Fn::ImportValue:
Fn::Sub "${IAMStack}-CodeDeployServiceRoleARN"
Outputs:
S3BucketName:
Value: !Ref S3Bucket
Description: Name of S3 bucket
I think some quotes may be off in your version.

Answer 2

Issue fixed, I just change the region
