As you look at your TV Fool report, pay attention to the 'Real Channel' column... Real channels 14 and higher are UHF. There are two separate bands of VHF channels and therefore not all VHF antennas are designed to receive all VHF channels. the L-VHF band includes real CH-2 through CH-6 and the H-VHF band includes real CH-7 through CH-13.
So based on the limited information available, it would appear that you need UHF and H-VHF capability. If every signal comes from the same direction, a single combination antenna may work very well... but it's unclear what your situation looks like.
WNEM – real CH-22, UHF
WDCQ – real CH-15, UHF
WEYI – real CH-30, UHF
WJRT – real CH-12, H-VHF (The weak NM value suggest that you'll need a dedicated H-VHF antenna such as the Antennacraft Y10713 pointed directly at this signal. Attic mounting is quite unlikely to provide reliable reception of this signal.)
WSMH.-- real CH-16, UHF (Also very weak, indicating the need for a full size UHF antenna such as the Antennas Direct DB8E. Attic mounting is quite unlikely to provide reliable reception of this signal.)
You did not include WBKB – real CH-11, H-VHF (If you want this signal, it's quite weak and will need the largest available antenna or possibly a tall mast or tower.)
I have no way to suggest how to aim due to the lack of that data. Both of the antennas I've mentioned are quite directional. They can be combined using an RCA TVPRAMP1R which has separate inputs for UHF and VHF. Or, you can use a passive UHF/VHF signal joiner ahead of a single input preamp. If you have signals arriving from multiple directions, you may need to consider an additional UHF antenna that terminates in an auxiliary tuner. Combining two antennas that cover tha same band, but are aimed for reception of different signals will generally be difficult or impossible to combine.
