Elizabeth
Considering she's a kindergartner and taller than CC I think she's at least 4, 2 being one of the tallest in her entire class.

CC I'm thinking at most he's possibly 3,12 - 4,0 exact.

Michael considering in Fnaf Vr the dresser is art least 6,0 thanks to Funtime Freddy. Plus also considering that Mike seems to be shorter than Funtime Foxy judging the view we get when we're walking in the auditorium. I'm thinking he's 5,0 5,3

Which also would apply to William since they seem to look alike as far lore says.

Mrs Afton there's no where to say exactly how tall she is but I think she's at least 5,2 at the most.

Charlie considering her age and the fact her Theodore is the size of a toddler. I imagine she's at most 3,4 - 3,6. She doesn't seem to be the tallest in her daycare/preschool.

There's no where to say how tall Henry is but I feel he's at least 5,5 and his wife is taller than him 5,9.

I don't know what this is supposed to be. :T
