External button interface design

Hi, I made this schematic for my project of connecting multiple push buttons via TS/TRS/TRRS (mic jack) don’t ask why i didn’t just use TS lets just say check before you buy :man_facepalming:. 1 thing im not sure about is the 10k pull-up resistor do I only need that one or 5 (one for each button). if I made a mistake can you tell me about it, im very new to this so any feedback would be appreciated. btw I use kicad.
