Not part of the industry... but maybe I can get you started.
If I had those antennas onhand now, I would first do some testing to see which channels I could pick up on which antennas. All three of your antennas appear to be UHF-only models... the Super-G is out of production, but appears to be a formidable antenna from the description here:

The 7697P seems to be the least sensitive, so I would start with that.
You possibly have enough antennas that you can pick up all three directions using separate antennas (18,48 at ca 30, 24,25 at 220, 13,22 at 326). I'm thinking you may as well use all your antennas, and combine the signals either at an A/B switch or at separate tuners under the control of a HTPC. The HTPC can give you a live feed from any of the tuners, and act as a DVR server.
That leaves 13 WVNY to be picked up by a dedicated VHF antenna like the Antennacraft Y10713. Put the Y10713 on the same mast as one of the UHF antennas and mix that signal into its UHF downlead, either with a passive combiner or a mast-mounted preamp with separate UHF and VHF inputs.
Your recpetion environment is challenging, but you already have a lot of setups that you can test, since you own so many antennas.
On mounting the Super-G, I have not done it, but I would picture it on a tilt-up mast. Tilt the mast down, secure the antenna to the end of the mast, tilt up the mast and secure with the tripod struts or guy wires.
