Hello Abhinav, Thank you for reaching out to us.
As for your question (Do I need to wait for all existing users to be deleted from the existing custom audience (user list) before adding new set of users ?), as per best practices, you would need to complete first that delete request before adding new users. There are instances wherein multiple processes are trying to update the same entity at the same time. With that, you might encounter the CONCURRENT_MODIFICATION error.
