Welcome to the forums!
All Pentax DSLRs except for the medium format 645d and 645z (also the Q series can't, although they are mirrorless and not DSLRs) can use K mount lenses natively (The K01 also uses K mount, it was a mirrorless).
That means most of the Pentax digital cameras will work with your lenses. Anything with a K in the name. Just avoid anything with a Q or 645.
The new K3iii has the most convenient features for shooting with manual aperture lenses (those with no "A" setting on the aperture ring), but older bodies can use those lenses as well, with a pretty easy metering step. Lenses with an "A" on the aperture ring, whether manual focus or autofocus, should work with all K mount digital bodies.
If you let us know what your budget is, tell us precisely which lenses you are planning on using, and maybe include what styles of photography you're into, we can probably give more targeted advice.
