SLR Nikon F lenses compatible with modern DSLR?

My dad has three nikkor lenses that he used with the Nikon FG and Nikon F4 - are they compatible with Nikon DSLR cameras? I don't know anything about them except one is a telephoto, another zoom, and another micro. All three have "rabbit ears".

They won't meter or allow AF, but they will fit a modern Nikon.
