  In this second paper on the investigation of extraplanar diffuse ionized gas
in nearby edge-on spiral galaxies we present the actual results of the
individual galaxies of our H-alpha imaging survey. A grand total of 74 galaxies
have been studied, including the 9 galaxies of a recently studied sub-sample
(Rossa & Dettmar 2000). 40.5% of all studied galaxies reveal extraplanar
diffuse ionized gas, whereas in 59.5% of the survey galaxies no extraplanar
diffuse ionized gas could be detected. The average distances of this extended
emission above the galactic midplane range from 1-2 kpc, while individual
filaments in a few galaxies reach distances of up to |z| ~ 6 kpc. In several
cases a pervasive layer of ionized gas was detected, similar to the Reynolds
layer in our Milky Way, while other galaxies reveal only extended emission
locally. The morphology of the diffuse ionized gas is discussed for each galaxy
and is compared with observations of other important ISM constituents in the
context of the disk-halo connection, in those cases where published results
were available. Furthermore, we present the distribution of extraplanar dust in
these galaxies, based on an analysis of the unsharp-masked R-band images. The
results are compared with the distribution of the diffuse ionized gas.
