Need opinions on these red pines

I bought a property about a year ago that used to be an old tree farm. I’m in northern Indiana and have a wide variety of trees, including these red pines. Invasive vines choked out a lot of trees. I’ve been doing a lot of clearing and have saved the red pines in these photos. I’m wondering if they’re healthy enough to keep or if they’re too tall and spindly to be healthy in the long term. Any opinions would be greatly appreciated.
