Answer

In Finnish in different situations you use different suffixes.

Oletko valmis? = Are you ready?

Onko sinulla kylmä? = Are you cold

Onko sinulla nälkä? = Are you hungry

For example if you want to say "I'm hungry" 
It's "Minulla on nälkä."

Quick summary for you:

Oletko = Are you

Onko sinulla = do you have

(If you have more questions do not hesitate to ask them I would like to help. Also I'm a Finnish language learner)

kiitos Karima, it solved my problem :)

Answer

onko sinulla is different then oletko sinä for example 'onko sinulla koulu' means do you have school?  and 'oletko sinä oppilas' means are you a student. so basically onko sinulla means do you have and 'oletko sinä' means are you. hopefully this hepls.
