My guesses 3.Luna, 2 Leni, 1.Lily.

Luna is one of the nicest and closest to Lic but she had jerk moment in It's a 7xLoud House and it was heartbreaking after For Bros about to Rock. Leni is the nicest of the siblings and she almost never argued with Linc. Lily has never insulted Linc and never argued with him and only she tolerated all his hobbies.
