Is there any taxi counters at Kunming Airport?

Hello, there seems no special taxi counter, but official taxis are available at the Arrival Hall. But a car can only accommodate at most 4 adult passengers. For your case, the private cars offered by locals can be acceptable, and they are safe too, but the cost can be a little higher. Or you can even book airport pick-up service in advance. If needed, try to search the service of TravelChinaGuide, which I used last summer.
