In the bottom photo, left to right....
Yes, on the left that appears to be a projector lens. I have no idea what it fits. I doubt it has much worth unless you can match it up with a specific projector model, then might get a few $ for it on eBay. Not many people using projectors these days!
Next to it appears to be 28-135 Vivitar, probably a Series 1. That's likely a pretty decent lens.... It's probably a Tokina-made lens, based upon a Konica design. I suspect the current Canon 28-135 is based upon this design. Many manufacturers copied the original one... First sold as a Konica Hexanon made by Tokina, then as Tokina AT-X Pro lens for some other manual focus mounts, then sometimes relabelled as Vivitar and perhaps some others, in a variety of MF mounts. The first two digits of the serial number of old Vivitar often gave a clue as to who actually made them (Vivitar never has made much themselves, they just hire someone else and have the Vivitar name slapped on... Not that they are alone doing this or that it's necessarily a bad thing). Just looking at it, I can't be sure what the mount is... Those lenses were offered to fit many different manufacturers' cameras. It's certainly not an EF mount, though, since it's a manual focus lens. It might sell today at auction for $50 - $100... but honestly I haven't tracked prices lately.
Next to that is the CPC zoom lens. Proably not a particularly high quality lens. Again, can't be sure of the mount. Might get a few $ for it on eBay.
Finally, that appears to be a Canon FD "New" 70-210/4 on the right in the last photo. Good lens, but the old FD mount and not really adaptable to the modern EF mount. Might sell for around $50 or more, depending upon condition. I've seen really nice ones sell for as much as $70 or $100 in recent years.
So, Dad probably got a good deal and you might get back hid investment and more on Craigslist of eBay. But none of the lenses appear to be usable on any modern EF mount Canon camera.
