What is the flux though each of the surfaces

What is the flux though each of the surfaces:

I got:

Surface 1: -q/ε
Surface 2: -q/ε
Surface 3: 0
Surface 4: 0

 

[indigojoker]

is this correct?

I have no idea what your question is! What flux are you talking about? The electric field due to those charges? That would depend on the precise position of the charges as well as the precise definitions of the 4 surfaces, which I cannot get from the picture.
