Not sure about the last file you downloaded but The Dark Wraith's mods are sub folders within the archive.
If you haven't named the JSGME sub folder in your SF5 directory "MODS" then the mods won't extract in a workable way (JSGME won't be able to put them into the game).
Open the archive file you've downloaded, look inside, you'll find a folder called "MODS." Copy all the subfolders inside that folder to the one you have created in the SH5 directory to hold your mods and then enable them with the JSGME installer.
Hope this helps.
