Well, I like to think I know a lot about cats, but number 1 and 4 have me stumped, I think because they may not be that accurate. 2 is definitley leopard, 3 is definitely jaguar, and 5 is definitely cheetah. If I had to guess for 1, I would say oncilla (aka tigrina). 4 could be margay as suggested, but again I don't think it's a very good depiction (but maybe I'm just whining because they stumped me!).
I hope you are going to reveal the answers at some point.
Great challenge Orycteropus, surprisingly tough though. My attempt:
Margay?, Leopard, Jaguar, different subspecies of leopard or a leopard cat?, and cheetah.
I'd definitely assume that #1 is ocelot, #2 leopard, #3 jaguar and #5 cheetah. Only #1 and #4 should really pose much of a problem, and so I'll guess that #4 is a margay. It could be a leopard cat as well...hmmm.
