As far as I know, Alfred Wünnenberg (seen in the first picture) is the only SS general known to have worn Lampassen with his uniform trousers. (Unless we count Peter O'Toole in Night of the Generals, that is.)
This was a personal affectation and strictly non-regulation, as these stripes were never authorized for SS generals. Apparently, this practice was a deliberate carryover from his days in the uniform of a police general. (If I recall correctly, Wünnenberg was actually not enthusiastic about having to wear an SS- rather than police uniform and had to be expressly ordered to do so by Himmler.)
The two men in the center of the group seen in the second photograph are police generals wearing the regulation green stripes for their rank group.
Julius Schaub, seen in the third picture, is wearing the evening dress uniform [Großer Gesellschaftsanzug], whose trousers had aluminum braid stripes (rather than normal cloth Lampassen) for all officer ranks.
