Default Airway pressure, Intrapleural pressure and Pulmonary cap Pressure

I have confusion reagrding these to aspects

At FRC ie. end of Normal expiration
1) Airway pressure or alveolar pressure will be 0
2) intra-pleural pressure will be -5


What about Pulmonary Capillary pressure??? will it be lowest at end of normal expiration(FRC) or at end of normal inspiration

please do explain the concept? thank you
