Is the supply capable of 5*32 = 175A? If 60-100A SP domestic you could never run all at max for any length of time anyway!
As above, generally your are looking to have as-installed CCC of 20A and it seems the issue is the grouping factor if it applies or not. As @timhoward says you would be best to try and avoid having the cables too tightly bundled for various reasons, the potential derating due to group factor being a significant one!
