A posted speed limit of 55 mph does NOT mean that you may drive 55 mph on that highway under all conditions. The top posted limit is for ideal conditions. But when driving, the conditions never completely stay at ideal. You must use common sense and judgment to lower your speed as necessary.
It means that there is a maximum speed of 55 and you are not allowed to pass it, if done so you may be fined or taken to court.
No, only undere ideal conditions. You are expected to reduce your speed to fit the prevailing conditions at the time.
The speed limit is the top speed that is legally allowed. If it is exceeded, you are breaking the law.

Whatever the posted speed limit is.
Varies by jurisdiction. Ultimately, it will be whatever speed limit is posted.
The minimum will vary by locale, but will normally be either 40, 45, or rarely 50 mph for limited access highways. The minimum speed on the Interstate Highway System is either 40 or 45 mph and is set within each state based on road conditions and traffic levels.
No, especially it's raining or for other inclement weather. Even if you drive the posted speed limit on highway you could be issued a traffic citation for driving too fast for conditions.
No. The posted speed limit of 55 miles an hour means you can drive a maximum of 55 miles an hour when it is safe to drive at that speed. Only an idiot would drive at that speed in fog and high wind.
No, it does not. If you're driving at 55 MPH and conditions make it unsafe to do so, you may be cited for failure to adjust speed to conditions.

Whatever the posted speed limit is.
No. If the road conditions make it unsafe to travel at that speed, you can be cited for failing to adjust your speed to the road conditions.
No, you should not. Your speed should depend on the weather conditions, and you should only drive a speed that is safe according to current visibility and road conditions.
Only under normal traffic conditions. During periods of heavy traffic, inclement weather, low visibility, or other poor driving conditions, speed must be adjusted so that accidents will be avoided.
