We present a comprehensive analysis of strong-lensing, weak-lensing shear andmagnification data for a sample of 16 X-ray-regular and 4 high-magnificationgalaxy clusters selected from the CLASH survey. Our analysis combinesconstraints from 16-band HST observations and wide-field multi-color imagingtaken primarily with Subaru/Suprime-Cam. We reconstruct surface mass densityprofiles of individual clusters from a joint analysis of the full lensingconstraints, and determine masses and concentrations for all clusters. We findinternal consistency of the ensemble mass calibration to be $\le 5\% \pm 6\%$by comparison with the CLASH weak-lensing-only measurements of Umetsu et al.For the X-ray-selected subsample, we examine the concentration-mass relationand its intrinsic scatter using a Bayesian regression approach. Our modelyields a mean concentration of $c|_{z=0.34} = 3.95 \pm 0.35$ at $M_{200c}\simeq 14\times 10^{14}M_\odot$ and an intrinsic scatter of $\sigma(\lnc_{200c}) = 0.13 \pm 0.06$, in excellent agreement with LCDM predictions whenthe CLASH selection function based on X-ray morphological regularity and theprojection effects are taken into account. We also derive an ensemble-averagedsurface mass density profile for the X-ray-selected subsample by stacking theirindividual profiles. The stacked mass profile is well described by a family ofdensity profiles predicted for cuspy dark-matter-dominated halos, namely, theNFW, Einasto, and DARKexp models, whereas the single power-law, coredisothermal and Burkert density profiles are disfavored by the data. We showthat cuspy halo models that include the two-halo term provide improvedagreement with the data. For the NFW halo model, we measure a meanconcentration of $c_{200c} = 3.79^{+0.30}_{-0.28}$ at $M_{200c} =14.1^{+1.0}_{-1.0}\times 10^{14}M_\odot$, demonstrating consistency betweencomplementary analysis methods.
