Why do all my philodendrons have spots after I brought them inside!

My White Knight, White Wizard, PPP, ROF, and a random red one idk what it is. I'm afraid for my Jose Bueno and Tortum. I have a baby Billie and a Joepii that are just props but they are touching the spotted guys. Anything I can do to protect the new growth? It looks so bad I'm devastated.
