This is the second of a series of papers on low X-ray luminosity galaxyclusters, in which we present the $r^\prime$, $g^\prime$ and $i^\prime$photometry obtained with GMOS-IMAGE at Gemini North and South telescopes forseven systems in the redshift range of 0.18 to 0.70. Optical magnitudes,colours and morphological parameters, namely, concentration index, ellipticityand visual morphological classification, are also given.  At lower redshifts, the presence of a well-defined red cluster sequenceextending by more than 4 magnitudes showed that these intermediate-massclusters had reached a relaxed stage. This was confirmed by the small fractionof blue galaxy members observed in the central regions of $\sim$ 0.75 Mpc.  In contrast, galaxy clusters at higher redshifts had a less important redcluster sequence. We also found that the galaxy radial density profiles inthese clusters were well fitted by a single power law.  At 0.18 $<$ z $<$ 0.70, we observed an increasing fraction of blue galaxiesand a decreasing fraction of lenticulars, with the early-type fractionremaining almost constant. Overall, the results of these intermediate-massclusters are in agreement with those for high mass clusters.
