The coldest temperature that anything can reach is –273.15 °C. That is called "absolute zero". On the Kelvin scale, which uses the same divisions as the Celsius scale, it is zero, making the point at which water freezes 273.15 °K. Absolute zero is the point at which all atomic movement ceases, i.e. the atoms no longer move relative to one another.
Any material can be heated or cooled to any temperature, as long as enough energy can be added or removed to do so. Materials left in an environment for long enough will reach the same temperature as their surroundings. This is known as reaching equilibrium with the environment.

When two materials with different temperatures are brought together they are equilibrating their temperature at a a temperature which is intermediate.
But there are some materials which are equilibrating quickly. These are good conductor of heat.
For some others , it takes a long time. These material which keep the temperatures are called insulators

Yes the theoretical limit is absolute zero (0K). Every material can be brought down to the same temperature as another, the only difference is energy required to bring fixed masses of different materials down. I.e., different materials need different amounts of energy to lower the temperature by a certain degree.
This energy needed to bring the temperature of 1 kg of mass of a certain substance by 1K is called its specific heat capacity.

There is no limit, other than, as mentioned, Absolute Zero which is 0 degrees Kelvan. At this point all motion and atomic activity ceases. All materials can be supercooled down to this temperature.

The lowest temperature that can be attained is 0 degrees Kelvin or, -454 degrees Farenheit (-273 degrees Celsius). At this point, all atomic motion ceases.

yes, there is a limit, the coldest situation could be attained is -273 Centigrad degrees, ie 0 Kelvin degrees
