In therory all Pentax K mount lenses should fit on the K110; but that is not to say all will perform 100% Im not a pentax man, so do you know anything else about these lenses, how old they are, are they AF or manual etc? If they are Af then they should be fine, if they are manual then they will fit but you will have to focus manually (dur) and probably "stop down meter" (or whatever the correct term is now, I always forget), meaning you will need to open then to their widest apertaure to focus and meter and then reduce the aperature to what you want before you take the shot.
What lens do you have on the K110 at the moment? Im guessing somewhere around 18-55 or so? The 80-200 will be a nice change then, with the added zoom. A decent 50mm prime is always a nice lens to have, and f1.7 will be great fopr lowlight portrait. Not really used a 28mm prime so cant comment on the usefullness on those really.
