That second (fourth) video has the same issue as the one I pointed out (possible to have this with a ferromagnetic material), but it's also possible we're seeing different things at once, or even novel *magnetic behavior. I don't have an alternative explication for the pointy side video though, so it could be Meissner effect or diamagnetism. In general it seems like diamagnetism could be consistent with all these videos? So thanks for pointing this video out :) My knowledge of these behaviors comes from what I know of ferroelectrics, which are different, and playing around with magnets like everybody (and then some), so my observations are in no way authoritative. I remain cautiously optimistic though :)
