Quite. Not the clearest of pictures!
I don't know eggs about those Humu cruiser things, but I think the first of the two is maybe a 1993 Cinder Cone in the US-only colour called Charcoal Metallic. The spiral on the head tube looks vaguely like the 93 colours, and the frame could be similar to the one below.
Not a bad $100's worth at all, especially if that Quadra is functional.
