Here is a list of all monuments coordinates except Brezovica.
It is partially based on @Aleks G’s link and @davidvc pastebin of it, however, some coordinates there are misleading. For such ones, the proper coordinates were found and the source or proof is given.
Petrova Gora (45.316426, 15.805206)
Grmeč (44.687329, 16.4376500)
Ilirska Bistrica (45.568796,14.240245)
Košute (43.627796, 16.691636)

Korenica
according to link it was destroyed and its location was 44.6765 15.8521:
I’ve been to Korenica and asked a dozen of people in the village, they
say it has been torn down. You may correct me if I’m wrong. But I’ve
spend half a day looking for the monument.

Makljen (43.842705, 17.597120) (source: annotated in Wikimapia as "destroyed monument")

Brezovica (missing)
So far: it is likely not in Brezovica. This image is from Pinterest and it is annotated as "1st PARTISANS BRIGADE MONUMENT in Brezovica, Croatia", however,there is only a "Monument to Sisak Detachment" (depicted below, source Wikipedia, location 45.502663 16.458433)
UPD: as @phoog noted there are many places named Brezovica (list of them in Wikipedia). The Wikipedia article for one of them (Brezovica, Kosovo or Брезовица_(Штрпце) in Cyrillic) contains picture of the monument:
Ostra (43.911496, 20.516597)

Nikšić (42.763139,18.959556)
Zenica (44.244945,17.960287)
For more see "Yugoslav World War II monuments and memorials" in Wikipedia.
These are old Yugoslavian War Memorials (or at least most of them). Somebody created a great google map overlay of these:
https://www.google.com/maps/d/viewer?mid=zxPqN7FUTnEs.kTu_C4z_ZK5c
for some reason I am struggling to get the exact coordinates from that map, but you can zoom in all the way on each of them to see the actual monument at a decent enough zoom level.
