I just purchased a D90 from a friend of mine. I have 7 lens that go back a bit. 2 are D series AF, one is an E seies lens,and the rest I beleive are AIS lens. All have the 5 contacts pins in the back of the lens.
I tried all the lens in the D90. 3 of the lens when I tried to turn then to lock them into the body felt like they were to tight. I was afraid to force them in. These lens are, A 28mm 2.8,a 50mm 1.8 and a50mm 1.4. They all fit my D300 fine.
