Asteriods can have any shape imaginable. It all just depends on the angle the other meteor hit it at.
If the asteroid is large, its own gravity will pull it together, into a more or less spherical shape. With smaller asteroids, the gravity is not large enough, and the shape will be irregular.
Niether, its a `Dwarf Planet`. Its much larger than an asteroid, able to hold itself into a spherical shape.
A dwarf planet is larger, big enough to make itself into an approximately spherical shape. Asteroids are smaller and more irregular in shape.

If you mean the shape of the orbit, it's an ellipse.
Ceres is the only asteroid to qualify as a "dwarf planet". It was the first asteroid to be discovered. It is more or less spherical in shape. It contains about a third of the total mass of the main asteroid belt. It may have water under its surface.
It couldn't as it's mass causes it to be spherical. To be like an asteroid, it would have to be the size of an asteroid, and then life would never have started. You would never have been born, and this question would never have existed.
It's part of the definition of "planet". An asteroid or meteor can have any shape, because its gravity isn't great enough to crush it into a mostly-spherical shape. But planets ARE massive enough that they have to be spherical; their gravity forces them into that shape. If their spin is fast enough, the equatorial regions will bulge out, such as with Earth and especially with Jupiter.
Ceres
They are not spherical
They are all irregular in shape due to their small size and corresponding low gravity. All except for one, called Ceres. Ceres is the biggest one and is just big enough to pull itself into an approximatly spherical shape - it is therefore classed as a dwarf planet.
That will depend on the exact shape, and the material it is made of.You can get an estimate, by assuming a spherical shape, calculating the volume, and multiplying that by some density (for example, the density of water). The actual mass may be a bit more than that if its a rocky asteroid; a bit less if it's ice, for instance.
