The term "blue moon" does not refer to the color, but to an occasional fourth full moon in a season (normally there are three), or alternately, to a second full moon in a month (usually there is one).
He could only make out four of Jupiters' largest moons.
A month on Earth is based on the amount of time it takes for the moon to make an orbit. Uranus has at least 27 moons, each with a different orbit time, so a month on Uranus doesn't make much sense.
No. Only the larger moons are spherical. Smaller moons do not have strong enough gravity to make themselves round and so are irregular in shape. Perfect example are Phobos and Deimos, the two tiny moons that orbit Mars.

Nothing extraordinary happens. Though not very frequently, there will be two full moons in one month due the the moon's cycle and our calender system. By the way, the second full moon of that month is called a "blue moon" (that's where the phrase "once in a blue moon" comes from). It is interesting that there are other ways to define Blue Moon. See link for more information.
The term "blue moon" refers to the extra moon that falls in a month that has two full moons. Each 2.7 years there is a month that has two moons in it and this rare event (actually the first moon in this month) is referred to as a "blue moon." The phrase, "once in a blue moon" means something is rare.
The Earth takes 24 hours to make one full rotation. It varies from month to month, but on average it takes 29.53 days for the Moon to make one revolution around the Earth, this is the same for the period of time between two full moons. The time between two high tides is about 12 hours and 25 minutes.
It doesn't make sense to talk about a "Mercury month". Here on Earth, the month is defined by the Moon's revolution around Earth. At least, that's what the term "month" meant originally. There is no equivalent on Mercury, which has no moons. Of course, you could use any arbitrary time period and call it a "month", but there is no generally agreed-upon "month" for other planets, whether they have moons or not.
There are 12 months in a year, 10 years in a decade and 100 years in a century. A month is roughly based on the period between two full moons (a very ancient way of measuring time) and a year is the period the Earth takes to make a full circle around the sun.

With the knowledge that scientists know, it wouldn't make a difference.
It depends on the terms of the contract, but probably.
It does have a full moon, but not a blue moon. It kind of doesn't make sense why it doesn't.
Approx 2.75 moons.
