  In the present paper II, we will gain an understanding of the nematicity,
insulating ground state (IGS), nematicity to stripe phase transition, Fermi
pockets evolution, and resistivity temperature upturn, as to be metal -
insulator (fermion-boson)- crossover (MIC) phenomena for the pseudogap (PG)
region of cuprates. While in the paper I [1], we obtained an understanding of
the observed heat conductivity downturn, anomalous Lorentz ratio, insulator
resistivity boundary, nonlinear entropy as manifestations of the same MIC. The
recently observed nematicity and hidden magnetic order are related to the PG
pair intra charge and spin fluctuations. We will try to obtain an answer on the
question: why ground state of YBCO is Fermi liquid oscillating and of Bi-2212
is insulating? We will also clarify the physics of the recently observed MIC
results of Lalibert\'e et al. [2] and explain the long-discussed transition of
the electric charge density from doping to doping+1 dependence at the critical
doping. We predict that at the upturns this density should have the temperature
dependence $n\sim T^3n_2$ for $T\rightarrow 0$, where $n_2$ is density for
dopings close to the critical value. We understood that the upturns before and
after the first critical doping have the same nature. We will find
understanding of all above mentioned phenomena within the PG pair physics.
