As FL says, the houses are shown against the planet symbol in the "aspects" table - person 1 horizontally and person 2 vertically. So, person 1 sun is in (their) 5th and person 2 sun is in (their) 10th, etc
. BUt, you need a chart diagram to see clearly which house person 2 sun falls into in person 1's chart (and vice versa) - although this information is in the tables.
I'd do a "circular chart" (synastry type) at astro.com :-

(Selecting "click here to show the chart" should take you to a page requesting the input details/birth data for person1 and person 2).
