They're M42 screwmount lenses. With an adapter, they'll go on Pentak K-mount, Canon EOS (not Canon FD, IIRC) mount, and Four-Thirds mount, but they won't be much use except at smallish apertures on the Four-Thirds.
They'll also go on some other mounts, go look it up. (I found they were M42 mount by running a websearch for them. You could, too.)
If your father's camera won't take them, get yourself a cheap Pentax Spotmatic film camera off e-Bay and it won't even need an adapter. Just film.
There's also some indication, however, that the 135/2.8 was also produced in Pentax K-mount, in which case get a cheap Pentax K-mount camera and an adapter for the other one. You can do your own research for that; I can tell you the best one you could get for film is an LX and the best you could get for digital is a K20D, but do your own research if either of those is out of your budget.
You can tell if it's K or screwmount because the screwmount one will be like a screw. Let us see the bottoms.
The 50mm is a normal, which means it roughly approximates human vision. The 135mm is indeed a tele, it compresses spatial relationships, relative to human vision.
They're worth taking pictures with.
Here's one for auction, for instance, found through a Google search:
http://cgi.ebay.co.uk/Revuenon-50mm-f1.7-fast-prime-lens-PK-fit-+-sky-+-caps_W0QQitemZ270245011554QQ cmdZViewItem?IMSfp=TL0806141121a32728
They passed through a German mail order camera company named "Quelle" which rebranded stuff it sold as "Revue," lenses as "Revuenon," so there's no telling where it came from, at least with my five minutes of websearching. That auction suggests Tokina for that 50mm, but it could easily be wrong.
This should be enough to get you started. Get yourself to the search engines.
