Consider a piece of ice floating in water if the ice melt then what happens to the water surface height ( it goes lower, upper or with no change)

What about when I don't let the ice come upper that the water surface when it is not completely melted?

There are 2 possible outcomes for this situation...
One is that the water level will stay the same
The other is the water level will lower
If the ice is just left there to float around, then the water level will stay the same
If the water level was completely submerged(there is a force holding the ice completely underwater), the the water level will lower. This may sound wierd, but let me explain. Ice has a density that is less than that of water. Ice has small air pockets. When the ice is completely submerged, that much water is displaced. When the ice begins to melt, the trapped air is released and the air floats to the top. This means that there is less matter underwater. This means the water level begins to lower.

Well, it will make no difference
The point is that the floating piece of ice will replace a quantity of water equals to its weight, which is the submerged volume of the ice piece.
Now, if the ice melts it turns into water but with the same mass and a different volume, this quantity of water will replace a quantity of the water which equals in mass to the Piece of ice and the replaced water.
Here we can see that there is no change in the level of the water, if the ice is completely floating in the water and the temperature is uniform

no change. The volume of the system does get smaller, but the water level is unchanged.
The frozen water is less dense than is the liquid - it float ON the water. When it melts, the system's combined mass is not changed, only the density, which gets larger from the melting ice to water.

There will be no change. The natural boyancy of ice (which is lighter than water) is exactly compensated by the volume of the melted ice.

there will be no change in the water level due to the fact that ice weighs more than the water, hence no change to the level or height of the water

Once the ice melts, the water level should actually lower, because the water molecules expand when it freezes and becomes ice, when the ice melts the molecules get closer together and thus take up less space.

it doesnt change because the volume of the ice does not change, the mass it takes up is still the same, just in a different form, so it would stay the same it is just less dense

if the ice melted the water level would rise. the density of a liquid and a solid are different therefore the surface area would be different

when you put the ice in the cup it goes higher but when it sits there in the water it doesnt change

no change. the weight of the ice does not change only the volumn it occupies above the water level
