Well, as I said before, your Zn's are just wrong. They would only be consistent with the Sun right at sunrise or sunset --zero altitude.
Here's a nice place to check your work:

Let's try your first sight. I enter your lat, lon, set the date, and enter 14:14:26 for UT. The let it do its thing, and I see 37d 32.3' for Hc, which is close to your altitude (given corrections, especially SD), so that's good. And the Zn is 123.5 degrees, a long way from the 91 that you found. You'll find similar discrepancies, I think, for your other sights. Again, I suspect you have somehow calculated the azimuth for the Sun at zero altitude. These things happen! Stange, but true. :)
Fix your Zn's and you should get a nice fix.
