De nada

What are your hours?

• Qué son tus horarios?

What time do you open/close?

• A que hora abras/cierres?

Are you open for dinner/lunch/breakfast?

• Estás abierto para la cena/el almuerzo/el desayuno?

Are you open on weekends/holidays?

• Estás abierto los fines de semanas/días festivos?

How late are you open?

•    Hasta que hora estás abierto?

Let's answer your questions:

1) I would use the construction, "¿Cúal es?" Also, it's perhaps clearer to use the bank as your subject rather than the individual with whom you are speaking. Your best bet is, "¿Cúal es el horario?" or "¿Cúal es el horario del banco?"

2) It is not necessary to change the verbs from their present tense form. Here again, though your meaning is understood and is perfectly fine colloquial Spanish, the bank would make for a better subject.

3)Fine sentence!

4) Aside from the plural "semanas" this is a fine sentence.

5) Fine sentence!

Could you offer an example sentence?

The sentence “se cierran los bancos temprano” – “The Banks are closed early” uses a grammatical structure which is usually not taught at the elementary level, but it is a very common structure and I would like to give you a few examples.

se habla español – Spanish is spoken (singular)

se hablan dos idiomas – two languages are spoken (plural)

se cierra el banco temprano – the bank is closed early (singular)

se cierran los bancos temprano - the banks are closed early  (plural)

se vende – it is for sale (singular)

Sí se puede – yes it can be done                                                             

If you want to find more information on this structure, you can google “impersonal se”
