Define "largest".
If going by mass, the three largest are Neptune, Saturn, and Jupiter.
If going by diameter, the three largest are Uranus, Saturn, and Jupiter.
The reason for the switch is that Neptune and Uranus are practically twins, but Neptune is slightly denser, making it smaller in diameter but larger in mass.
There are 184 moons in our Solar system, counting ones associated with dwarf planets. The largest moon, Ganymede, orbits Jupiter. Mars' two moons are so small that they are not even round.

The opposite of "least" is "largest" or "greatest". However, note that there is no such thing as the largest counting number.
All of the planets in the Solar System except for Mercury and Venus have at least one moon.
Mercury is the smallest planet in the Solar System
By volume, the planets' size in order from largest to least is: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, and possibly Pluto if you like to consider it a planet. By mass, it is the same list, except for the fact that Neptune is more massive than Uranus.
Mercury, Mars, Venus, Earth, Uranus, Neptune, Saturn, Jupiter.
No. Most planets do. Six of the eight planets in our solar system have at least one moon.
