I have to be honest. It's hard to comment on the animation and pose for the Help action (also used in one spell casting animation)... because it's kind of hard to tell what it's Supposed to be in the first place.
I'll do all four here first, starting with human male, since Human Male is the most complete animation set, and is clearly the character for whom all poses and animations are designed for first. Human males don't have any misalignment or statics, for example; everything animates and lines up more or less correctly for them.... so let's have a look...
So... On the human male, it looks like a partial crouch pose, while you're... I guess, holding onto one of your arms, like it's hurt... but also making an open handed, ready-style gesture with the hand of that arm, held low. What's going on here? I'm just not sure.
Human male has some slight foot clip on uneven ground, but otherwise seems to line up correctly. Human females have developed a slight misalignment, and are clipping slightly through their chest (clipping against the chest can be done well; depending on what you're wearing it can be made to look like you're just compressing things a bit - this doesn't manage that; the arm would need to come up a bit to clip in way that might look like you're just squishing yourself a bit).
Halfling female... that does not track at all well, and male halflings, yikes! Not sure where to begin with that, beyond the pictures themselves, though I'll point out an easy to miss problem, if you get distracted by the more obvious ones - the female's halfling's foot is several inches floating off the ground, in the air.
