Allfour inner planets: Mercury, Venus, Earth and Mars.
Slightly more or less than 92 million miles.
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
Mercury, Venus, and Mars.
One Astronomical Unit is the shorthand name that astronomers gave to the distance between the Earth and the Sun. Venus is closer to the Sun than the Earth is; it averages about 108,000,000 kilometers, or about 0.72 AU, from the Sun.
It is a bit less than a quarter of a million miles from the Earth to the moon.

The earth and Mars move in different orbits around the sun at different speeds. Therefore there is no single numerical answer to the question. There is however a minimum and maximum. See the link below.
All planets in the Solar System are less than 2 billion miles from the Sun, except for Neptune, which is 2.8 billion miles away.This answer does not consider Pluto, because it is no longer considered to be a regular planet.
The minimum distance is approximately 54,500,000 km (34 million miles). The farthest the Earth ever gets from the Sun is 152 million kilometers and the nearest Mars ever gets to the Sun is 207 million kilometers. So Earth and Mars could, very rarely, be a little less than 55 million kilometers (34 million miles) apart, when they are directly in line with the Sun. The closest recent distance was in 2003, when they were 56 million kilometers at closest approach.
Slightly more or less than 92 million miles.
None is, really. The planet capable of approaching Earth at the smallest distance is Venus, which at some times can be less than 26 million miles away. I would still not want to be required to walk it ... That's like around the world 1,034 times !
All of them do.

Your question isn't really clear. Can you re-word it? The earth and moon are close to each other, relatively speaking. The moon is only roughly 240,000 miles from us. That is less than one quarter of a million miles. The sun is a whopping 93 million miles from us.
If you could cross space directly and ignore Newton's laws like in Star Trek, You would need to cross between 54,710,000 and 401,307,000 kilometers depending on the current orbital/precession status of both planets. However, since current Earth spacecraft burn and coast into an elliptical orbit around the sun such that Mars' gravity will catch the spacecraft; the travel distance to Mars is less than about half of the circumference of Mar's orbit, or about 715 million kilometers, and more than about half of the circumference of the Earth's orbit, or about 470 million kilometers. Differences in designs of spacecraft can change these numbers drastically. Hence it is usually easier to simply refer to the direct line-of-sight distance between the planets.
