So I have three pushbuttons each with a +5v input, output to pin via resistor and a pulldown resistor to ground. They work great but I'm wondering if I wouldn't be able to just use 1 pulldown resistor to stop them from floating or if this would cause them to not function properly if they were presse…

Multiple pushbuttons and pulldown resistor

No, just create the interrupt on a Low level instead of High.
