Bigfoot and the Orang-Pendek are the most likely for me. Also, possibly Vietnam Rock Apes. There are lots of stories from US soldiers in Vietnam about them. (Some reported "Rock Apes" turned out to be Red-Shanked Langurs, but there were a lot of reports of upright hominid-like animals, too)
IMO, Lock Ness Monster is impossible, and the Jersey Devil and Mothman are horrendously improbable.
If you consider the Thylacine a cryptid, I also think they could still exist.
I have been really into Bigfoot lately and there is a lot of evidence for Bigfoot. None of it is really 100% solid, but it's there. Some anecdotal claims and stories are just absolutely mindblowing, and I've heard a lot of stories that almost seem to indicate government knowledge of a relict hominid in the US. It sounds like real tinfoil hat type stuff but some of it seems pretty sincere.
