The first one is nice. Not as flashy as the original mare, but a cute jumper and a decent enough mover (definitely not the hack winner, but not awful). I'm not really seeing anything about her in the video that would make me love her. In fact, I'm really not a fan of seeing her counter bending to the first jump. I like her still shots though. She's at least worth checking out.
The second one is very narrow through the chest. Aside from that I can't tell much because there aren't even pictures of her doing anything. All her tacked pictures show her in a figure 8 bridle, which you can't have for hunters, though I suppose the pictures were taken while doing cross country.
The last one is cute to look at, but doesn't look too clean with his knees. He is also listed as having a temperament of 7 and needing an intermediate/advanced rider, which is worrying for what it sounds like you want.
