As far as we know, none of them is, although planetary scientists are still not sure about Mercury.
Aside from Mercury, the one that comes closest is Jupiter, which is inclined only 3.1° from perpendicular.
Earth's axis is inclined 23.5° from perpendicular.
The champion and weirdest planet of all is Uranus, with an inclination of 97.8° from perpendicular.
Neither; the ecliptic, the plane of the Earth's orbit around the Sun, is inclined to the galactic plane by about 60 degrees. The galactic plane is easy to see; it is the path of the Milky Way across the night sky.
Yes, the axis of rotation of Mercury is nearly perpendicular to the plane of its orbit around the Sun. This means that Mercury's axial tilt, or the angle between its rotational axis and orbital plane, is very small.
No, the Earth's axis of rotation is at a twenty three and a half degree angle to the plane of its orbit, which is closer to being perpendicular than it is to being parallel. This 23.5 degree "axial tilt" are responsible for, among other things, our seasons.
Rotation of UranusUranus's axis of rotation lies on its side with respect to the plane of the solar system, with an axial tilt of 97.77 degrees.
Uranus's axis of rotation is tilted at about 98 degrees from the perpendicular to its orbital plane. This means its axis is roughly in the plane of its orbit. It looks as if it's rotating "on its side" so to speak. So rotation is clockwise when viewed from "above " the plane of its orbit. ("Above" is the direction above the Earth's North Pole.)

the earth is not perfectly round, as with most other planets it is an oblate spheroid. Answer: The tilt refers to a tilt in the axis of rotation, compared to a line that is perpendicular to the Ecliptic (the plane of Earth's orbit around the Sun).

Uranus is the planet whose axis of rotation is almost perpendicular to the plane of its orbit around the Sun. This unique orientation of its axis causes extreme seasons on Uranus, with each pole experiencing 42 years of continuous sunlight followed by 42 years of darkness.

The planets don't all orbit the Sun in EXACTLY the same plane - there are small variations. The plane where Earth orbits is called the Ecliptic; other planets orbit fairly close to that same plane.
This refers to the Earth's axis of rotation; and the tilt (which is about 23.5°) is measured from a perpendicular to the Ecliptic, i.e., the plane of Earth's orbit.
There isn't one. They all orbit in roughly the same plane. Pluto orbits in a different plane, but that's not classed as a planet now, of course.
