Negative pitch would not make sense.
pitch range specifies the variation of the speaking voice from the average

A negative value for stress might make sense in certain situations
--typically, this value specifies the level of emphasis
on stressed syllables --and its effect is added to the result of applying
other rules, so a sophisticated system might want to set stress to a negative
value in order to offset some other effect-- though I would consider this
rare.
Ditto for richness
So in summary:
negative values for pitch and pitch range are probably meaningless
they might make sense in the case of stress and richness in certain situations.
