The best time would be in the morning or evening.
A1C cannot be lowered overnight
Fasting blood sugar (in the morning, before eating) should be Less than 100 mg/dL. 1-2 hours after a meal should be Less than 140 mg/dL. And 2-3 hours after eating should be Less than 100 mg/dL
It is possible to have high A1C levels without diabetes in rare cases. Iron, folate etc can also increase HBA1C levels.
Yes, they both can be compared.
