Help me identify these pines & tips for development

[mthelm85]

I picked these pines up last year in the discount section of a local nursery (just a regular nursery here in western Washington) and I am hoping someone can help me identify the specific varieties. Right now, I'm just following general pine care/development guidelines, but I know it can vary depending on the exact species I'm dealing with. One question I do have right now, though, is whether there's any problem leaving the 2nd one (2a, 2b, and 2c in the photos) in the large nursery container to continue its development there. I was planning to leave it there until the top is a little further a long, and then gradually reducing the roots over time as I repot it into progressively smaller pots. Is this fine?

It is extremely difficult to ID pines just from foliage and new shoots.
One of the first Id features is the number of needles in each fascicle. It appears both your pines are 2 needle species. That still leaves several hundred possible species.
The brownish new shoots on pine 2 remind me of Mugho pine but there are lots of American 2 needle species I'm not familiar with. I can also see that one has back budded well down the trunk on old wood which may also be a distinguishing feature that someone else may recognise.

First pine has very yellow new shoots but green older needles. Just wondering whether the golden shoots are normal of is it suffering some sort of nutrient deficiency?
There are a couple of golden foliage pine cultivars so if that's normal growth it may help with ID.

Pines tend to do better with less interference and more foliage so I'd agree with the plan to let it recover and grow before starting on root reduction.

Same to me. I can't tell if it has back budded on old wood or it's some kind of moss.
All my mugho pines have soft tipped needles, they don't feel prickly when you touch them.
