It wouldn't have occurred to me to tip for either of these. Unless the tour guide is a private tour guide arranged just for my group. The others seem high but absolute amounts will depend on your budget.
Fwiw my personal rule for restaurants for a meal with good service was 15% or $2 whichever was greater -- I always thought the waitresses in the cheap breakfast diners put more work in than the staff in the expensive restaurants and it never seemed fair that they got much less.
