How long can you see who has watched my Insta story? (Instagram, Snapchat, Social Media)

if I have something in my insta story I can see who saw it

but

in which order? So are the ones up there who saw it last or who saw it first?

and also important?

if you look at it again “does the position change” ??

It matters about my crush

wishes me luck ????????

THANKS TO ALL ANSWERS
