This question is impossible to answer.
As of today, 11th April 2011, there are over 540 known extrasolar planets - each one is different in it's own unique way.
The only answer, based on today's knowledge, is that none - so far - are like the inner planets but that is due to our technology rather than the actual planets.
Uranus
Extrasolar planets are planets found orbiting stars other then our own.
light from the they orbit makes it difficult to locate extrasolar planets with telescope
Most of the known extrasolar planets are more massive than Earth because massive planets are easier to detect. We have detected planets smaller than Earth.
Both exoplanet and extrasolar planet are planets that are outside the solar sysytem.
They least resemble rocky planets like Venus Earth and Mars, particularly they least resemble planets that we would consider as possible life sustaining planets.

Yes. So far nearly 2,000 extrasolar planets have been discovered.

About 100 extrasolar planets are thought to have been discovered. All are giants and probably most resemble Jupiter

Mars The inner planets such as Mars, Earth or Mercury. these are too small to identify in other systems and too close to the star.
The reason that most extrasolar planets are found close to their parent stars is that the amount and frequency of the star's motion are both higher in these planets.
