Scootcargops,
An-124 cargo hold dims are 36.50m long, 6.40m wide, and 4.40 high.
Your cargo:
1. 1@ 2800x300x300cm (12T)
2. 2@ 2800x100x150cm (3T) Each
3. 1@ 2800x100x150cm (2T)
4. 1@ 150x150x150cm (4T)
Your load will fit one flight if articles 1-2 can fit side-by-side next to each other (to give 5m wide?) and article 3 can be stacked on top. More than enough space to load article 4 at the front or rear.
Good luck
