How many fins are best for a rocket?

Three fins
Three fins are best when designing a high performance, low drag rocket. This allows interference drag (drag caused by interference of the airflow over the body and fins at the junction) to be reduced by 25 percent.

Is it better to have bigger fins or smaller fins on your rocket?

Rockets with a larger diameter have more drag because there is more air being pushed out of the way. Drag depends on the cross-sectional area of the object pushing through the air. Making a rocket as narrow as possible is the best way to reduce drag. The speed of a rocket through the air similarly increases drag.
