In fact, Venus, Uranus, and the "dwarf planet" Pluto orbit the Sun in the same direction as all the other planets. So all the planets orbit in the same way.
However they rotate in the opposite direction to the other planets.
The solar system has three classified dwarf planets. They are Pluto, Ceres, and Eris. A dwarf planet has sufficient mass, has not cleared the neighborhood around its orbit, and is in orbit around a star.
No. The planets CANNOT all "line up", because they all orbit in slightly different planes. We occasionally see one or two planets line up, but never more than three at once.
Shape, rotation-direction, and orbit-direction.
To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.
Due to gravitational forces by other planets in universe,earth changes its circular orbit into ellipse.it has enough tangential velocity to leave the orbit and go straight,but sun attracts it and vice versa.
Of the seven other planets that orbit the sun, three are smaller than Earth and four are larger.
Only 3 planets actually orbit the earth while the rest orbit around the sun. the three are mars venus and uranus.

Since it was discovered in 1930 by Clyde Tombaugh, many astronomers have felt uneasy about Pluto being called a "planet" for three reasons: (a) Pluto, with a diameter of 2275 km, is very much smaller than any of the other planets of the Solar System; in fact, it is only about two-thirds the size of our Moon. (b) Its highly elongated orbit is greatly tilted at a sharp angle to the orbital planeof the other planets; in other words, all the other planets revolve around the Sun at almost the same plane. (c) Furthermore, it is the only planet with an orbit that intrudes to the orbit of another planet (that of Neptune).The other outer planets are very large and gaseous. Pluto is very small, and doesn't have as much gas.

No, usually the planets are in different directions. Every few years two or three of them line up.
There are 176 known moons that have been discovered so far in our solar system. These are small bodies that orbit a planet or dwarf planet. 169 moons orbiting six planets (includes Earth's Moon) 7 moons orbiting three dwarf planets There are other bodies that orbit the Sun, or that orbit dwarf planet candidates. There are as many as 58 satellites of trans-Neptunian objects (TNOs) and around 104 asteroid moons (orbit around larger asteroids).
There are three things needed to qualify as a planet. A body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.
