I grew some Hallertau and Tett about 15 years ago and yanked them because they grew well but only produced a few handfuls of hops, just not worth it. The young leaves on both were mostly 3-lobed and the foliage was pretty dark. The Chinook I have growing is usually sort of lime-green as it begins to climb and turns darker once it's up to the top of the pole with most of the young leaves being 5-lobed and very 'blocky/square' looking from the edges to the tip as opposed to the Hall and Tett which were somewhat longer to the tip vs. width. I'd say that the plant on the left of your first picture is the Chinook. Once the cones form you'll be able to tell for sure as the picture that nagmay showed is very characteristic of Chinook with the ends of the bracts flaring outward. Grab a beer and watch them grow, should be a great year.
