Most objects in space attempt to hold a spherical shape, Spheres having the greatest surface area to mass ratio. But if we look at Jupiter's moon Io, it's actually 2 moons that collided and have left a peanut shaped moon. It's quite likely that through collision planets have done the same. At that same time, gravity will eventually wear any planet back down to a sphere, given enough time.

Yes. That's one of the criteria they recently established for planets (the ones under which Pluto got disqualified). A planet must be massive enough for its gravity to "flatten" it's shape into a sphere.

every planet in the universe (and Ive seen them all) is round.(all except the square ones)

No. The earth is slightly pumpkin-shaped. Other planets are similarily asymetrical, though not in precisely the same proportions.

The Earth isn't round. It 'bulges' slightly at the equator.

No, Pluto is dog shaped, Mars is a brown rectanglular shape and Neptune looks rather like a man holding a large fork.

Yes, but each planet has geographical features that define its shape.

yes all the rough parts have fallen off as it goes round

no, the earth is wider across the equator than it is over the poles. 'spherical' would be a better term

Yes...
Gravity natually creates spheres, all things being equal.
