Any lens ever made by Pentax will work on any Pentax dSLR.

The reverse is not necessarily the case; a number of nowadays lenses no longer have an aperture ring and older cameras might not have the option to control the aperture electronically. So those newer lenses fit but don't have full functionality.

Even more: Any Pentax-compatible lens ever made will work on whatever mount version it was made for and anything newer. BUT... those in screwmounts need a simple adapter. AND... there are a few problematic lenses. Some few Vivitar K-mount lenses have a an aperture-link shield that is too large for our dSLRs, but that's easily removed. And some Ricoh-made K-mount lenses have the infamous Ricoh Pin, which is also easily removed.

As sterretje said, newer lenses might fit onto older cameras but not have full functionality. And newer APS-C lenses may show vignetting on full-frame film bodies. Too bad I can't use my DA10-17 on my K1000. Not nicely, anyway.

Your candidate lenses are all fine. Buy and enjoy.
