I have 2 cloud accounts and only need one, how do I delete or cancel my account so I do not have to pay for the one?
By "account", I assume that you mean "Google Cloud Platform project", because a "Google Cloud Platform Account" is the same as a Google account, assuming you're referring to user credentials. You don't pay for such an account; you only pay for the resources you use, which are attached to a project.
You can easily delete a project from Google Cloud Console — once you delete it, it will delete any contained resources and you won't be charged for them.
Note that a project will not cost you anything if it is not consuming any resources.
Thus, there's no need to delete or cancel either your email accounts or projects. As soon as you stop using resources within a particular project, you will stop being charged for those resources.
To "close" your billing account:
a. Go to the Cloud Platform Console https://console.cloud.google.com/
b. Hamburger menu: select Billing.
c. Select the billing account name. (Do this twice.)
d. Click "Close billing account."
e. Type "close" to confirm.
Note: Google will not entirely "delete" your billing information:
"Upon checking, your billing account is still active. You will need to close it to prevent notifications being sent to your email. We cannot delete the details on your billing account for auditing purposes. Though rest assured that we take privacy very seriously. Once your billing account is closed, all the information will be encrypted and moved to a cold storage."

For some industry perspective, in terms of complexity, this is very unusual. Both as a consumer, developer, working at ISPs, I have never seen such a complex process to close a business account in my 20+ years of hosting. (Academia is another story.) This is not meant to be disparaging or a "rant." Depending on the type of work that you do, maybe complexity is exactly what you're looking for. I believe it's important to know what you're getting into ahead of time.
Shutting down a project in the console releases all resources used within the project.
To shut down a project:
Shutting down a project stops all billing and traffic serving, shuts down any Google Cloud Platform App Engine applications, and terminates all Compute Engine instances. All project data associated with Google Cloud and Google APIs services becomes inaccessible.
Google is charging for resource usage. If you delete a project, your project will not use any resource and you will not get charged.
