I want to make an drone with these motors: https://www.amazon.com/XtremeAmazing-2200KV-Brushless-2212-6-helicopter/dp/B01M3UBGU9

1: First of all, are they good? If not, could you suggest me other motors?

2: If they need 12V and their max power is 342W, is the max current is 28,5A?

3: If the max current is 28,5A/motor x 4 motors x 65% power = 74,1A?

4: If the motors take 74,1A and I have a 3000mAh battery, does this mean I can only use my drone for 2,43 minutes?

(3000mAh / 74 100mA = 0,04...h = 2,429min)

5: If yes, 2,43min is not a lot, how should I do to be able to use my drone for at least 15min without having to recharge the battery?

Your calculations assume that the motor will be running at full power all the time.

Assuming your quadcopter's weight is less than 4 times the max motor thrust (which it needs to be to have any control), then you won't be running at full power.
