Can I use adapted lenses on the pentax kp?

Yes, and you don't need an adapter for the Pentax KP. It uses the Pentax K mount, so old manual K lenses fit directly.

Its APS-C sensor has a 1.5 crop factor, so a 50mm lens frames like a 75mm on full frame. If you want to check other focal lengths, the focal length converter does the sums for you.

The Pentax KP page lists every lens that fits it. For a cheap, sharp standard prime, the Pentax smc FA 50mm f/1.4 is a good place to start.
