Applejack prayers crying: “Tony Stark, we’re all grateful for you to save the day. We hope that you will always be in our hearts. We will remember you forever. Goodbye, Tony, and thank you.”
James Rhodes: “My friend Tony is in better place from now on.”
Fluttershy: “He did bring everyone back and everything back to normal.”
Bruce Banner: “He sure did and proud of it.”
Peter Parker: “I will never forget you, Tony.”
Rainbow Dash: “Don’t worry, Steve. We’ll see each other again someday, as long as you will always be Captain America.”
Steve Rogers smile: “Thank you, Rainbow Dash.”

Both hug.

Thanks for the memories Friendship is magic its been one hell of a ride. You’ll be remembered

To me, it feels just as emotional as Mickey Goldmill passing away in Rocky III with Rocky holding his coach and crying his eyes out saying “We gots more to do” and right now… I’m gonna miss this show so much

Those busts were there in S8, so not necessarily them. If I had to guess at who might be gone, out of them, it’s probably Mistmane, due to how she’d sacrificed her beauty and youth.
 
As for Granny Smith? She’s dead. What Applejack is wearing easily implies that.

Oh yeah, the pillars don’t show up in person but in busts implying they have passed on since then.
