When this close to signals that are extremely strong, reception of otherwise easy signals calls for use of a high gain antenna aimed at the weaker signal. Amplifiers are going to make your problems worse, not better.
Your TVFR indicates the top dozen signals are overpoweringly strong... the top three are predicted to be able to overload a typical tuner.
You could try an Antennacraft Y10713 pointed at 145°. You may need to add an FM trap and attenuator with 10 to 20 dB of loss. I would try with no attenuator to begin with, the extremely powerful UHF signals are going to easily get in via the antenna even though it's designed for high-band-VHF.

In extreme cases (yours is approaching that) a second FM trap may be required.
