Can I set the lifecycle stage of a contact backwards?
Yes, you can, but keep in mind that the lifecycle stage property is not really designed to go backwards. The reason for this is because you generally want to move your contacts down the marketing funnel and once they hit one lifecycle stage, they can't really go backwards within that role: a customer will always be a customer. You can read our article here to learn about what steps you'd need to take to roll back the lifecycle stage of your contact.
Why is my contact import failing or returning an error?
In order to successfully import contacts from an external file into HubSpot, there are a couple requirements for this to be successful. For example, your external file must be a .CSV file and you must include an email address for each contact. There are a few other reasons your import could be failing, and you can read more about them here.
