Good question - the yellow ones do look weak. Did they have similar roots when you collected them? Am also curious if they all started the same color or if they were weaker to start with.
If they were about to fail, they'd look worse than they do. While they don't look great, they don't look too bad at this point.
Have you had much experience collecting lodge pole before?
As for what to do, the main thing is to watch the watering on the yellow trees. Not too much, though do provide water to the foliage every day. And while they can handle some sun, a full day of strong sun might be too much until they've established more roots.
