In the second paper of the series we continue the investigation of opencluster fundamental parameters using a robust global optimization method to fitmodel isochrones to photometric data. We present optical UBVRI CCD photometry(Johnsons-Cousins system) observations for 24 neglected open clusters, of which14 have high quality data in the visible obtained for the first time, as a partof our ongoing survey being carried out in the 0.6m telescope of the Pico dosDias Observatory in Brazil. All objects were then analyzed with a globaloptimization tool developed by our group which estimates the membershiplikelihood of the observed stars and fits an isochrone from which a distance,age, reddening, total to selective extinction ratio $R_{V}$ (included in thiswork as a new free parameter) and metallicity are estimated. Based on thoseestimates and their associated errors we analyzed the status of each object asreal clusters or not, finding that two are likely to be asterisms. We alsoidentify important discrepancies between our results and previous ones obtainedin the literature which were determined using 2MASS photometry.
