There is not quick copy and paste for resources in Azure. If you want to do this you can look at a few different options:
- Create Infrastructure as Code to deploy your resources, ARM Templates, Terraform, PowerShell DSC etc. This will be quite a bit of work, but it will allow you to spin up any number of environments you want from this code
- Use Azure Backup or Azure Site Recovery to backup the environment you create and restore it to another resource group
- Take images of your disks and use this to create new virtual machines in another environment
