Lucy is biologically 27 during the Philosopher's Stone, but physically 7 years younger than that.
She was 17 during Season 1 until the Tenroujima Sinking. 18 during the Grand Magic Games. 19 during the Alvarez War.
19+7 = 26. And it was already September 1st when the school year started so she's 27.
Lisanna
Like it was said in the first chapter, she came back AFTER the war not after the Edolas Arc. Truthfully, she did come back with the team, however, she was taken away for eight years hence she came back after the war.
But not as herself, it would be explained in the future chapters, like during the Goblet of Fire book.
