  The identification of young star groupings (YSG) in the three spiral galaxies
NGC 3377A, NGC 3507, NGC 4394 is obtained by mean of the statistical method
described in Paper I. We find 83, 90, 185 YSGs, respectively. An identification
map of YSGs, as well as their size distribution, their B-luminosity function,
their surface luminosity density radial behaviour, are presented and
comparatively discussed. These data, in addition to those in Paper I,
constitute a first sample suitable for seeking correlations among properties of
galaxies and their YSG, which we briefly discuss here.
