Almost all the Muslims I know sneeze/cough into their right palm & pick/blow their noses with their right hands. Is there anything wrong with using the left hand or a handkerchief?

I don’t know anything specific in this regard.
Muslims are instructed to use their right hand for honorable things and use their left for dishonorable things.
