The UHF section is a simple UHF Yagi structure with a parasitic element that is probably there to flatten the bandwidth.

The VHF section, is not a Yagi as the two rear most elements are connected to each other with phasing lines which excludes that section from being a conventional Yagi but is rather a log-periodic design. The two long elements clipped to the underside of the boom are probably there for the same reason as the parasitic element on the UHF side.
I agree.

The two long elements on the underside are parasitic directors for VHF-High, which would make the four rear elements a hybrid called a log-yagi for VHF-High.
