I've provide an example which may address this. I haven't tested it though.
You place the "How many people live in your household ?" outside of the repeat group, and then have a repeat group cycle through for the number of people in the HH.
Alternatively, you can just collect HH roster, and include your Q2 and Q3 in the roster Qs.
An example of the first option is attached (modified from @yanokwa's example HERE
