You can give multiple eviction notices, they do not cancel each other out. You can revoke a notice anytime. It is likely your first eviction notice will not stand up in court because it did not give the required 14 days to cure.
You cannot give a no-cause eviction notice if the tenant is on a fixed term lease. You can only give no cause notice if the tenant is a month to month or week to week renter. If the tenant has been renting from you for more than a year, you must give a 60 day no cause notice. Otherwise a 30 day will suffice. Notices are highly technical documents, I recommended a quick appointment with an attorney in your area to ensure the notice will be valid. The half hour appointment could save you hundreds in filing fees if your notice is even slightly deficient.
