I know that it can exist at higher temperatures than 0 degrees Celsius if the pressure is decreased, but is there a limit?

Yes, there is a limit called the "triple point", which is about 1 mm Hg and 0.1 deg C. At extremely high pressures (hundreds of atmospheres), the structure of the ice crystal changes, and ice also can exist at temperatures above 0 deg C.

Pressure 611.73 Pascals, at 0 degrees Celsius, ice, water and water vapor can excist. There are different kinds of ice that can be formed at different pressure, but all seem to be below zero.

There probably is -- at very high pressures, ice can exist at quite elevated temperatures, but I do not have data. This is the sort of thing which you can probably find in:

Do you mean when ice can exist or at which point it starts to melt? Because Ice in large forms take a while to melt....

24*c in Reykjavik, Iceland was the warmest temperature recorded at one stage during their summer.
