Explanation:

Device 1 is Windows 10 - and policy 1 is for Windows 8. Default compliance for devices without a policy is not compliant so first 2 questions are NO.
Then the third device has 2 policies, the first one is compliant and the second policy is not compliant but the device is not marked as non-compliant due to the fact that mark device as non-compliant is set to 10 days. This means that the machine will be compliant until june 10th.
Source:
Mark device non-compliant: By default, this action is set for each compliance policy and has a schedule of zero (0) days, marking devices as noncompliant immediately.
When you change the default schedule, you provide a grace period in which a user can remediate issues or become compliant without being marked as non-compliant.
This action is supported on all platforms supported by Intune.
