Getting one or two compressors will depend on your usage habits.
Some get 2 compressors due to they use all or most of the blowers unit at the same timing thus need both compressors to work to produce sufficient btu to power all.

What's the recommendation for a 5-room flat? Sys 5 or 2+3, or just sys 4 will do?
Setup 1
sys3:
2 common room - 9k btu
living room - 12k btu
sys2
MBR - 12k btu
dining room - 9k btu
Setup 2
Sys5
common room - 9k btu
MBR - 9k btu
Living Room - 12k btu
dining room - 9k btu
Setup 3
Sys4
common room - 9k btu
MBR - 9k btu
living room - 12k btu
Or any other suggestions?
Technically, is it looking the btu of the compressor will tell me how many unit I can switch on simultaneously by adding each unit's btu?
