Jupiter, Saturn, Uranus, and Neptune.
There are actually four inner planets. In order from closest to the sun to farthest, they are Mercury, Venus, Earth and Mars. The four outer planets in order are Jupiter, Saturn, Uranus and Neptune.
Mercury, Venus, Earth, and Mars.
It's because they are the furthest distance from the Sun. The other four are called the inner planets because they are the closest.
They are called the terrestrial planets, in order from the sun Mercury, Venus, Earth and Mars
The four outer planets are all significantly larger than the four inner planets. Beyond that there's no simple relationship. The size of the planets (from smallest, 1, to largest, 8) in order of distance from the Sun: 1, 3, 4, 2, 8, 7 ... and then it gets vague. If you go by radius, the last two are 6, 5 and if you go by mass they're 5, 6 (either way, they're nearly twins).

There are actually four inner planets. In order from closest to the sun to farthest, they are Mercury, Venus, Earth and Mars. The four outer planets in order are Jupiter, Saturn, Uranus and Neptune.
It's the same as the order of distance, because they follow Kepler's 3rd law, which says that the time to go round varies as the distance to the power 3/2. That means that the linear speed is inversely proportional to the square root of the distance, which means a planet four times further away would go at half the speed.
Very generally, the outer four planets are less dense than the four inner rocky planets, but it's more to do with planet type rather than their distance from the sun.
Our planets are numbered from the distance from the sun, so four or fourth.

Some are, but the furthest from the sun, Pluto, is also the smallest. The four innermost planets are considerably smaller than the four outermost, but the correlation of distance and size is not perfect. Earth is the largest of the first four planets, Mercury, Venus, Earth and Mars, even though Earth is number three. Jupiter is the largest of all, even though it is the first of the remaining four; Jupiter, Saturn, Uranus and Neptune. Pluto isn't a planet anymore, so you could say that
There is no real relationship between their diameter and distance from the sun, except that you could say that the four outer gas planets are much bigger than the four inner rocky (or terrestrial) planets.
The first four are the smaller `Rocky` planets, then the last four are known as the 'gas giants'. The gas giants are further out from the sun, with Neptune being the furthest planet away from our sun (in our solar system). Pluto is further out still, but since 2006 it has been downgraded to a 'Dwarf Planet', so is no longer a `planet`. There have been a few other dwarf planets discovered that are even further out than Pluto, but of similar size, such as Makemake and Sedna.
Mercury, Venus, Earth, and Mars.
The gas planets are the four outer planets; Jupiter, Saturn, Uranus and Neptune. They don't have a solid surface like earth, just gas that gets thicker and thicker the further you go in.
In order from closest to farthest from the sun, it's Mercury, Venus, Earth, then Mars
