Pentax 'M' series lens. Pentax has 'K' (which is not really K but just SMC), then M,A, F, FA, & DA. Plus a few others. So if someone says an M50 f/2 it means a 50mm f/2 lens from the Pentax 'M' series.
'K' is shorthand for the original Pentax K-mount lenses. They were not called that by Pentax and will show "SMC Pentax" on the lens. However they are commonly referred to as 'K' series to distinguish them from the later lens series's. So K24/2.8 is a 24mm f/2.8 lens from the original k-mount series.

I would look into getting your 24mm repaired. It might not be as bad as you think. I had a lens look like that, and it was just off the 'track' so to speak, I popped it back and it has worked fine ever since. NOT recommending you try that but a camera shop might be able to repair at less cost than getting another lens.
Assuming you are happy with it of course. If not, then try another lens. But if your widest is currently 24mm, then remember that 24mm is just a wide angle on APS-C. Ultra wide angle will be maybe 16mm and wider. So the UWA lenses like 12-24 or 10-20 might work, or the 15mm limited. But those are all much different than your 24mm. So if you like 24mm do not think that 15mm is better, it is very different.
