    I and II have pyrrole ring, so lone pair delocalised to ring makes it aromatic so less basic.. In II there is extra resonance with benzene ring makes it less basic than I. and II is least basic among all

    IV is most basic because lone pair is not involved in resonance

    while in III, lone pair is localised but there is -I effect of pyridine ring
