There is currently no evidence that there is a risk of a major eruption happening any time soon. While an eruption may be possible, it is unlikely to occur any time in the next ten thousand years. The most likely form of activity appears to be in the form of laval flows, but even these are unlikely to occur any time soon.
The Earth has existed in roughly its present form for about 4.5x109 years.
Hurricanes form in the summer time. If you look at the related link, you will find that hurricanes require warm water to form. In Florida, our hurricane season (time when hurricanes are most likely to form) is from June 1 to Dec 1, 2009.
Yes 3pm to 9 pm is the most common time for tornadoes to occur, though they can form at any time of day or night.

No. Stars do not all form at the same time. They have been forming since billions of years and many are forming even as you read this. They do, however, form in clusters.
