"What does Aamir have?"
Translation:आमिर के पास क्या है?
पास is a word that means 'near'. 'के पास' (literally 'near to') is a postposition that is used to indicate possession.
क्या has two uses:
It can be used to ask 'yes/no' questions. This replaces questions beginning with 'Is', 'Does', 'Are' etc in English. When used this way, क्या always appears in the beginning of the question.
It can be used as 'What'. In this case, क्या appears just before the verb in the question. In this particular example, since the only verb is है, क्या is written just before it.
Based of the sentences it seems पास is kind of like standing or sitting in that it's an adjectives rather than a verb. Can someone please confirm or explain?
It's neither an adjective nor a verb. 'के पास' is a postposition that literally means 'near'. Eg: घर के पास एक नदी है- 'There is a river near the house'
When used with people, it is used to indicate possession or ownership. Eg: मेरे पिता के पास बहुत पैसे हैं - 'My father has a lot of money' (literally, something close to 'With my father is a lot of money').
