Diagram a full and complete X$-$bar tree for $(5).$ Here are some things to help you:

$$ You will have one CP$-$TP$-$VP structure per V$.$

$$ Things like APs and PPs are almost always adjunct.

o X$$ mother, X$$ sister

$$ Things like direct objects and verb phrases are almost always complements.

o X$$ mother, X sister

$$ The nominative DP $($aka subject$)$ is a specifier of T$.$

o XP mother, X$$ sister

$$ The bracketed words are a DP; PP doesn$$t modify V here.

After you diagram $(5),($a$)$ draw a circle around one specifier, $($b$)$ draw a rectangle around

one adjunct, and $($c$)$ draw a triangle around one complement.

$(5)$ John believes that the boy in the bar loves $[$the girl in the bookstore$].$
