Without knowing the intention of the matrix you can't!
Firstly I think you should always assume that what is already in a column belongs there.
However, what you do know is that no column should contain only zeroes. So if one does a simple fix would be to replace it by the cross product of the other two columns renormalised to 1.
That way it will be orthogonal to the others columns but not large. If, as in the examples you give, the parts are flat and the third dimension is ignored then this will work perfectly.
This solution works for all the examples you give eg.

I think this would be the better solution.

Code:
M=[-2.84 0 -2.84 0 0 0 2.84 0 -2.84]
=[-2.84 0 -2.84
0 0 0
2.84 0 -2.84]
c1=[-2.84 0 2.84]
c2=[0 0 0] !!!! Needs fixing
c3=[-2.84 0 -2.84]
x=cross(c1,c3)=[0 16.13 0];
c2p=[0 1 0]> Any help would be appreciated.
