Went through the 18/19 year olds to check their age as of Day 1 of filming of each of their respective debut seasons.

Will Wahl: 18 years, 7 months, 23 days (Born: August 12, 1997, Day 1: April 4, 2016)

Julia Sokolowski: 18 years, 11 months, 22 days (Born: April 8, 1996, Day 1: March 30, 2015) [turned 19 on Day 10 of ]

Brandon Hantz: 19 years, 7 months, 15 days (Born: October 15, 1991, Day 1: May 30, 2011)

Natalie Tenerelli: 19 years, 3 months, 10 days (Born: May 6, 1991, Day 1: August 16, 2010)

Spencer Duhm: 18 years, 10 months, 12 days (Born: December 20, 1989, Day 1: November 1, 2008)

So Will was the youngest by nearly 3 months from Spencer, followed by Julia, Natalie, and Brandon.
