I-864 sponsor for parents

[Husbandandwife 35]

Hi guys, 
I have questions about filling up the form I-864 for my parents. Somebody who already filled it up could help me ?

1- Part 3 - 1 
I am the sponsor filling this up for my dad and my mom in separate forms. This correct if I mark on part 3, 1 ? See pic attached.

2 - Part 3- 4a
Should I fill something as family member 1 ? Like my mom’s name on my dad’s petition and vice versa ? See pic 2 attached

3 - Part 3 - 29 
Should I fill it as 1 or 2? See pic 3 attached

Thank you
