My brake pedal goes all the way down to the floor
but I only did one side so am I supposed to do two
Yep, bleed all four, since you did only one side and not the other and tried brakes out bleed all four, not just the other side, and if that does not do it see if there are any leaks, if not your master cylinder may be bad.
Bleed brakes in a certain order starting with the wheel that is furthest from the master cylinder. Order for your vehicle is passenger rear, driver rear, passenger front and driver front.
