Airfoil Wind Tunnel Data

I would recommend that you pick up a copy of the classic book Theory of Wing Sections by Abbott and Von Doenhoff, 1959. This is a very popular book summarizing the basics of all the NACA airfoil series, and it should be easy to find in a technical library or university book store. The appendices include lift and drag plots for a number of 4-Digit airfoils, although I'm not sure if it contains any of the airfoils you mentioned. The book also references many NACA reports that may contain additional data. Most of these reports are available on the web at the NACA Technical Reports Server.

Another option is to download Mark Drela's XFOIL code. XFOIL is one of the most respected codes in existence for computationally predicting airfoil performance. All the NACA 4- and 5-Digit airfoil coordinates are built into it, so analyzing them is relatively easy. The code is a little difficult to learn at first, but it's well worth the time.

Additional information on airfoil design and analysis is available in previous questions on airfoils.
