Created Apex Class and Lightning page component but it's not showing up under custom components when I try to "edit page". Looking for some help to see where I went wrong.

Below is what I have:
Apex Class

Lightning component bundle (component, controller, helper)

Hey all - I've researched enough to understand that what I need to do can only be done in Visualforce: displaying a text field based on picklist options.

Basically, I have 5 fields "RP 1, RP 2, RP 3, RP 4, RP 5" in a custom object "Staff Development" and they all are picklists that have the same options for answers (the 34 clifton strengths - basically I am trying to give everyone a place to identify their top 5 strenghts on a page).

Based on the answers in ALL 5 of these fields collectively, I want to display further information. So if the answers in the picklists include (order doesn't matter) Adaptability, individluzation, woo, empathy, and developer - then there needs to be 5 text fields (with default values) named Adaptability, Individualization, Woo, Empathy, and Developer that pop up that shows the description for each of those answers.

Again, doesn't matter which of the 5 "RP" fields is chosen that includes one of those strengths, if the picklist choice is chosen in any of the 5 picklist fields, that text field appears (normally hidden) and displays the information. 

Any help appreciated!
