cn i use this keyboard with my classroom pc tower?

if it has a USB port and you have permissions to instal a device...yes.

I don't have Fire TV, I uses it with my laptop that connected to HD LED TV.

Hello this keyboard is for android tablets and phones ??

This keyboard is for computers with USB ports, as it has a USB transmitter.

Will this work if i use Samsung galaxy s21 and tv monitor?

It's not a bluetooth keyboard. It has a standard USB transponder that you have to plug in to your device. Any device that you can use with a normal USB keyboard you can use with this keyboard. You can use it with a PS5 or most smart TVs. But probably not with a phone, and not with a TV that you're just using as a monitor. You'd have to plug it into the computer that you're using with the TV.
