How are adjectival pronouns declined when nouns of multiple genders follow? For example:
Jede/Jeden Höcker und Kurve in der Straße.
The nouns Höcker und Kurve are of different genders (masculine and feminine respectively) - but then, does the use of two nouns also make it a plural? How is Jede declined in this case?
You need two of them:
Jeder Höcker und jede Kurve in der Straße.
Jeder/Jede Höcker/Kurve in der Straße.
Normally, two nouns would make it plural. However, there is an exception when using jede, keiner, mancher. The verb that follows then requires the singular form: See here
Jeder Höcker und jede Kurve in dieser Straße führt dazu, dass man ständig abbremsen muss.
Every bump and every turn on this read cause you to break all the time.

Not at all! The word "alle" is used in that case, and it is not declinable for gender.
Alle Höcker and Kurven.
