In our solar system all the planets (and Sun) formed from one collapsing nebular. Therefore all the planets have the same stuff inside them. The differences between planets is caused by the differences in their outer layers as the planets formed at different distances form the Sun where the temperatures gradients allowed the condensation of different compounds.
When you consider Xenoplanets, we do not know hat they are made of exactly yet.
Jupiter is the largest planet in the solar System so any of the other planets could fit inside a volume the size of Jupiter, some of them many times over.
Jupiter
Jupiter is the planet in our solar system that is large enough for all the other planets to fit inside. It has a radius of about 69,911 kilometers, which is larger than any other planet in our solar system.
The "inner" planets are on the "inside" of the asteroid belt, while the "outer" planets are on the "outside" of it
They are both visible and inside the solar system.
The planets inside the steroid belt will get hit and the other planets will not.
well some planets are bigger than the earth but from the inside earth is of course bigger than all of the other planets

Because it is nearer to the Sun than all of the other planets. Its orbit is inside that of all of the other planets, so it shorter.
Yes. There have been hundreds of planets discovered in other stars in the Milky Way. It has been estimated that the Milky Way likely contains hundreds of billions of planets.

yes - dozens of planets are known to exist. Earth-like planets, however, are hard to detect. Most of the planets found have been giants like Jupiter and Saturn.

The earth is a planet, it has no known planets within.
no
You cannot have planets orbiting planets. Planets orbit suns. Only satellites orbit planets. In the case of planet Earth, the moon is the only natural satellite.
