Any AI, AI'd, E, AIS, AF, I, or S Nikkor will, though stop-down metering
may be necessary with some combinations. Non-AI lenses can be AI'd for
$30 to fit AI bodies by a few people - here is one:

Most "E" lenses are good-excellent, though I am not fond of the 28, 35,
or 36-72 (though they are not terrible, and are cheap). Most Nikkors
of any type are fine.

See above, or look back through related posts - it has been done many times....
