Accommodate for family

I'm starting FB meal plan round 1 - My family will be joining me in the adventure because I won't make two meals every day.

The grocery list is for one person, right? So I could multiply each amount of ingredients to make it for my husband and toddler?

For example, on week 1 list, it tells me to buy 4-5 apples, but that's just for ME right? So I should buy 10+ for my husband, toddler and myself?
