Comets do indeed have orbits. Sometimes the orbits take thousands of years. For the most part, they stay in these orbits unless affected by the gravity of another body.
Because they are trapped in the gravitational of a star that they orbit...very long orbit.
By and large they do. The orbits may be perturbed and they could become open orbits.
They are in elliptical orbit

elliptical
Virtually NOTHING in space is in a circular orbit; every body out there is in an elliptical orbit. Some are CLOSE to circular, but I don't believe than any are quite exact. Comets especially are in VERY elliptical orbits. If their orbits were even nearly circular, their ices and volatile gasses would have been evaporated long ago.
Comets have sharply turning, elliptical, oval-like orbits, as opposed to the rounder, more circular shape of a planet's orbit
The Oort Cloud
Planetary orbits are usually taught to be circular. However, they are truly more elliptical (oval shaped).
No, most comets do not have a circular orbit in the space between Mars and Jupiter. The majority of comets originate from two regions in our solar system: the Kuiper Belt and the Oort Cloud. These regions are far beyond Mars and Jupiter, and the comets from these regions follow highly elliptical orbits that can take them close to the sun or far into the outer reaches of the solar system.
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.

All orbits are geodesic curves. Comets tend to have elliptical orbits ... as do planets, really; the degree of eccentricity (this is a measure of how "stretched" the ellipse is) just tends to be higher for comets.
Comets travel in highly elliptical orbits. See link for more.
yes yes Yes, comets and asteroids usually follow elliptical orbit.
The Earth orbits in the plane of the ecliptic in an ellipsoidal orbit that is nearly circular. Comets orbits are highly elliptical and mostly out of the plane of the ecliptic.

Yes some elliptical orbits are more circular than others
Comets. Periodic comets have highly eccentric elliptical orbits, with eccentricities.
