    in your case the focal axis is the y-axis

    Write the equation of a hyperbola with vertices at (-4, 0) and (4, 0) and co-vertices (0, 5) and (0, -5). x2/16-y2/25=1 - correct?

    The symmetry of a hyperbola with a center at (h, k) only occurs at x = h. True?

    yes correct, for example we can consider the cas h,k>0, so we have this drawing: |dw:1439651855400:dw|

    another symmetry, as you can see from my drawing is with respect to the axis y=k

    it is false, since the symmetries occur with respect to these axes: x=h y=k
