James Cook did not "discover" Tonga, but he first visited the islands in 1773, whilst on his second voyage. Tonga was discovered by two unnamed Dutch explorers in 1616. However, Dutch trader/explorer Abel Tasman is often given the credit, as he was the first known European to land there, doing so in 1643.

Yes and no. Cook was instructed to search for the great southern continent. He found the east coast of Australia, although the western half of the continent had already been found, but the continent was not the huge land mass he was expecting to find.

James Cook's original mission was to observe the transit of Venus from the vantage point of Tahiti. Cook was then under secret orders to try to find the great unknown southern continent, and claim it for Britain. In so doing, he charted the eastern coastline of what he called "New South Wales" (now Australia), making extensive notes on the people, flora, fauna and prospective suitability for colonisation, and reported back to England.
No. James Cook was unsuccessful in finding a northwest passage.
The first voyage of Captain James Cook on the HMS Endeavor was a south Pacific Ocean expedition to observe the 1769 transit of Venus across the Sun. A dual purpose was to find evidence of an unknown southern land.

No such name. If you were looking for Captain James Cook, well, he never went to Antarctica He was on his voyage to find the mythical 'Terra Austrialis'. A 'great southern continent' that nearly entirely covered any land from 40 to 90 degrees south. He did travel close to Antarctica on hid third and final voyage, but never actually 'got there'.
