It’s more likely that you’ve desoldered something than you have destroyed it after touching with the soldering iron.
Have you got some good magnification to take a closer look at these resistors?
Also take a multimeter in Ohm mode, and check the values, like said above if the resistors are in a circuit the value will be wrong, in which case it doesn’t tell you anything, but if the value is correct it will tell you that in all likelihood they are not damaged.
Also use the multimeter to check for continuity between the resistors and other parts of the PCB they are connected to (try to follow the tracks, or best try to get the schematics). That would tell you if they are any bad joint.
Finally check for shorts, it’s really easy to add too much solder to a switch and inadvertently short it.
