the first and third entry will be Carlsruhe /S (Schlesien = Silesia) which is quite likely to be Pokoj in Silesia now; the second entry ist Militzsch - now Milicz in Lower-Silesia. With this information you will easily find the places in any online map.
These were easy to read, but normally a wider clipping would be helpful to compare the individual handwriting of letters for transcribing.
