What are the conditions required to change matter from one state to another state?

The conditions required to change matter from one state to another are temperature and pressure. On increasing the temperature of matter the kinetic energy of the molecules also increases. This leads to a change in state.

Is heat added or removed in freezing?

To cause freezing energy must be removed. Because you are removing heat to freeze a substance it is called a exothermic change. The point at which this happens is called the freezing point. Freezing points and melting point happen at the same temperature it just depends on whether you are adding or removing heat.

When matter changes its state what happens to its mass?

If the number of atoms stays the same no matter how they are rearranged then their total weight stays the same. In all physical and chemical changes the total number of atoms remains the same hence when substances interact with one another combine or break apart the total weight of the system remains the same.
