taxis from Wusongkou international cruise terminal to People's Square

1. When we depart from Wusongkon international cruise terminal at the morning, are there any taxis or vans available outside the terminal to take us to the People's Square?
2. We have 4 people and 4 luggage, do we need 2 cabs?
3. How much it will cost for a cab or van?
4. The taxis cost based on # of people in a taxis or per trip?
Thankyou. Waiting for your response.
