Yes, as long as the extension cord is rated for the load. Most microwave ovens use 1000W or more, some less. A standard two wire extension cord would be unsafe. There are, however, extension cords which have the proper gauge of wire and the necessary 3-prong outlets which a microwave would need to operate safely.
15A should be the max needed for household versions
The most common wire size for an extension cord to use would be a #14 conductor. As extension cords are classed as flexible cords, the proper terminology would be a 3C/14. The cord consists of three #14 conductors, whose colouring is white, black and green covered by a plastic sheath.

No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.

Are you saying that you plug in a lamp and another lamp on that extension cord goes dimmer? If so then the extension cord wire is of a smll guage size and causing a voltage drop from the outlet to the cord output.
Yes. It should be a 'heavy-duty' extension cord, rated for 15A or 20A .

Yes, and extension cord can be used with a microwave. But it is critical to pick an extension cord with a sufficiently high rating on it. Hardware stores and large home stores have extension cords specifically for use as appliance extension cords. They are heavy, and they have only a single place on the end to plug something into. They cost a bit, but are worth it in peace of mind.
You can plug an extension cord into another extension cord. A extension cord is to help make doing something easier.

If you are talking about the gauge of the wires, then no. Larger guage wires( numerically lower) will pass current required for the appliance with lower losses, so it is better in that reguard Less resistance= less waste( in the form of heat). If you are talking about LENGTH, then yes. The longer the cord, the more losses that occur. Voltage lowers, so current goes up. If the extension cord can't pass the required current, then voltage remains depressed, and you end up with an appliance and extension cord that are running hotter, and less efficient. Worst case; fire.
