Piano pedals??????????????????

I have a Tokai Upright piano and I was just wondering, is the mute pedal bad for the tuning or the piano. with some notes it makes it sound kind of bad when i use the damper pedal. is it ok to use the damper pedal as well as the mute pedal? also is it ok to use the una corda or soft pedal as well as the mute pedal? and is it ok to use the una corda pedal as well as the damper pedal. and lastly what about all at once? thanks. btw any tips?
also, is it a big deal that when i use the mute pedal it makes a little squeak noise?

Hi!

It’s OK to use pedals one, two, or three at a time. Pedal use is definitely not bad for the piano.

And if a pedal squeaks, it needs some lubricant, the same as you would use on an office chair.

Good luck!
