Jupiter,Saturn and Neptune's rings are different from Uranus' rings,which is tilted 90 degrees(I think).My question is why?

The answer to your question is that Uranus was "tipped over" on its side by a collision with some other object BEFORE the rings were formed. This is an astronomical adaptation of the geological Law of Superposition.

Most of the planets spin on an axis nearly perpendicular to the plane of the ecliptic but Uranus' axis is almost parallel to the ecliptic. At the time of Voyager 2's passage, Uranus' south pole was pointed almost directly at the Sun. This results in the odd fact that Uranus' polar regions receive more energy input from the Sun than do its equatorial regions. Uranus is nevertheless hotter at its equator than at its poles. The mechanism underlying this is unknown.

Actually, there's an ongoing battle over which of Uranus' poles is its north pole! Either its axial inclination is a bit over 90 degrees and its rotation is direct, or it's a bit less than 90 degrees and the rotation is retrograde. The problem is that you need to draw a dividing line *somewhere*, because in a case like Venus there is little dispute that the rotation is indeed retrograde (not a direct rotation with an inclination of nearly 180).

Uranus With Rings

The rings orbit its equator just like the other ringed planets. The difference is that Uranus has a tilt of almost 90 degrees. Since they follow the plane of the equator, the rings are horizontal depending on your point of view.

Becuase Uranus rotates vertically

the rotation of rings denotes the planets magnetic axis. It's distance does not let the "plane" of gravity reach it...
