First one, possible fir. Check and look for remnants of cones. Firs, the cones point up, the cones sit on the top side of branches. FIr cones disintegrate after seed is ripe. Needles tend to be blunt & flattened for fir. Spruce the cones hang below the branch. The cones can hang on a season or two after the seed is ripe. The cones "point down". Needles tend to be sharply pointed, though not always. Which fir you have? I don't know. Abies concolor and Abies lasiocarpa are both native to Oregon, but their ranges don't seem to overlap. In a location, you have one, or the other. Both have range overlap at 7,000 feet. A. lasiocarpa tends to be at or above 7,000 feet, and Abies concolor tends to be at or below 7,000 Feet.
Second one, the pine, my first guess would be western white pine - Pinus monticola - which is found in central and eastern Oregon, or Pinus albicaulis the white bark pine - the whitebark pine has very limited distribution in Oregon, but it does occur in the Northeast corner of Oregon, or it could be sugar pine - Pinus lambertiana, but lambertiana is mainly found in Western Oregon, not eastern Oregon, if the range maps are accurate. It is unlikely to be limber pine, Pinus flexilis, because flexilis is not found in Oregon.
SO for the #2, the pine, my stronger guess is Western White Pine, Pinus monticola.
I do not think it is one of the bristlecones. I see no resin channels on the needles. The "foxtails" of foliage are not as pronounced as I would expect for a bristlecone.
FOr pines, details of where prickles occur or don't occur on cones is often key to separating species. It is beyond my depth, but just going by Wikipedia I would say #2 is Pinus monticola.
