There are a number of ways you can use this set of curves to produce a continuous surface. One way is to select Surface / Loft from the Rhino main menu. You should see the message 'Select curves to loft. Press Enter when done'. Start selecting the curves from back to front as shown below by left-clicking on each curve, making sure the selections follow a linear sequence (selecting curves out of order will result in lofting a more complex curve).
When you have finished selecting all the curves, press Enter. Accept the defaults of the Loft Options dialog. A surface will be lofted upon the curves that you selected. This should appear something like that below.
Selecting the Shade option and Zoom Extents All will produce a moveable, rotatable surface such as that shown below.
