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 H₀. 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 H₀^–1=14Gyr (H₀=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 H₀ can be recovered to a precision of 5%. In combination with COSMOGRAIL Paper I (Eigenbrod et al., 2005A&A...436...25E) on the temporal sampling of lensed quasar light curves, the present work will help to optimize the strategy of the monitoring campaigns of lensed quasars.
