If all 1.5 billion people in China jumped at the same time would the earth be thown out of its orbit?

No. That is not physically possible. The mass of 1.5 billion people is miniscule compared to the mass of the Earth. Moreover, their push against the earth when they jump up would be counter-balanced by the gravity of the people who jump, along with their force when they land. The net effect would be virtually zero.
