My favourite would definitely be the K 50 f4, followed by the DA 50, the K 55mm and the Auto Revuenon. The K 50 f4 gets by far the most use. The DA is for when I am being lazy, and the other two I use for special purposes as and when required. Special mention must go to the A f2.8, but since the acquisition of the K 50 f4 it does not get much use. The other M and A models were acquired by default through camera purchases over the years and I would be happy to let them go, just have not got round to it.
It seems I forgot to mention a couple of close to 50mm. Pentax HD DA 40mm and Auto Revuenon 45mm f2.8. Also no mention of all my non K mount close to 50mm's. So belatedly here we go...
