The pattern I see is that you confuse number and gender.
- *Estos libro → It is not written in the plural because it speaks <u>only</u> of a <u>book</u>.
- Esos plato → It is not written in the plural because it <u>only</u> speaks of one <u>dish</u>.
- Aquellos carros → It is not written in the singular and masculine because it speaks <u>many</u> <u>cars</u> (masculine).
- Aquellas casas → It is written in <u>feminine</u> because it talks about some houses (feminine).

A los estudiantes no les gusta la tarea.
A ti y a mi nos interesa el arte
A ella le aburre el fútbol
A ti no te falta nada
Here you go :) I believe this is all correct
