Here are the remaining answers:

5. 9 = P. in the S.S. (planets in the solar system)

11. 9 = J. on the S.C. (justices on the Supreme Court)
12. 10 = D. in a T.N. (including the A.C.) (digits in a telephone number (including the area code)
15. 15 = M. on a D.M.C. (men on a dead man’s chest)
16. 3 = S. Y. O. at the O. B. G. (strikes you’re out at the old ball game)
17. 200 = D. for P. G. in M. (dollars for passing “Go” in Monopoly)
18. 8 = S. on a S.S. (sides on a stop sign)
19. 3 = B.M. (S.H.T.R.) (blind mice (see how they run))

28. 64 = S. on a C. (squares on a checkerboard)
37. 15 = M. of F. per P., A. to A.W. (minutes of fame per person, according to Andy Warhol)
42. 4 = H. of the A. (Horsemen of the Apocalypse)

Sadly for me, I tried to change the "1" in question 14 to "2" last night, but was denied.
