As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
In one word 'YES'. The paths that you describe are the planets orbits. These orbits are shaped like 'Ellipsoids'., that is an ellipse that doesn't quite close-up , but overloops with every circuit. The Sun lies not at the centre of the ellipsoid, but at one of the foci. As a consequence planets following their orbits paths speed up (Nearest the Sun) and slow down (Furthest from the Sun).
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
All the planets in our solar system move in elliptical orbits around the Sun. This means their orbits are not perfect circles, but rather slightly elongated shapes.

Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
All planets have elliptical orbits.
Yes
maybe
Orbits move in very elongated elliptical orbits.
Yes some elliptical orbits are more circular than others
Planets move around the sun in elliptical orbits. These orbits are elongated and follow Kepler's laws of planetary motion, which describe the shape and dynamics of the planetary orbits.
