Explanation:
In Spanish we use "Qué" in question form, when we don't refer to a specific group ir thing, and we use "Cuál" on the opposite, when we refer to something or a group, and "Cuales" is the plural form of "Cuál" referring to more than one thing. As you can see, number one isn't refering to something in particular, is the equivalent of "What are you doing?" and number three is mentioning a long or short dress... Number two is the plural "gafas" glasses.
The verb estar is an irregular verb, that means, it does not follow the pattern of all other "regular" -AR verbs.
The verb estar means "To Be" for temporary characteristics.
Think LCP (Large Cheese Pizza)
L- Location
C- Condition
P- Participle.
Those are when you use estar.
