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
A1C cannot be lowered overnight
It is possible to have high A1C levels without diabetes in rare cases. Iron, folate etc can also increase HBA1C levels.
Eating before A1C test wont affect the results.
Yes, they both can be compared.
