  Aims: To predict time delays for a sample of gravitationally lensed quasars
and to evaluate the accuracy that can be realistically achieved on the value of
H_0.
  Methods: We consider 14 lensed quasars that are candidates for time-delay
monitoring and model them in detail using pixelized lens models. For each
system, we provide a mass map, arrival-time surface and the distribution of
predicted time-delays in a concordance cosmology, assuming H_0^{-1}=14 Gyr
(H_0=70 in local units). Based on the predicted time-delays and on the
observational circumstances, we rate each lens as `excellent' or `good' or
`unpromising' for time-delay monitoring. Finally, we analyze simulated time
delays for the 11 lens rated excellent or good, and show that H_0 can be
recovered to a precision of 5%.
  Results: In combination with COSMOGRAIL paper I on the temporal sampling of
lensed quasar light curves, the present work will help design monitoring
campaigns of lensed quasars.
