One TX and many RX

I have no experience with 433MHz wireless but you can certainly do what you say with nRF24L01+ transceivers.

If you are only interested in 433MHz wireless (which would be a perfectly reasonable thing) please modify your Original Post and add "with 433MHz wireless modules" to your title.

It would also be a good idea to post a link to the datasheet for the modules you plan to use.
