We use 'still' to talk about something, a situation or an action, that's continuing, often for a longer time than expected. It hasn't changed or stopped. 'Still' usually goes in the middle of the sentence, before the verb.

Are you still married to him?
Is she still unemployed?
I'm still living with my parents.

We use 'yet' mostly in questions and negative sentences. Using 'yet' shows that we're expecting something to happen or have happened. In spoken English 'yet' almost always comes at the end of the sentence or question and is commonly used with the present perfect.

We use 'already' to talk about things that have happened, often earlier than expected. It usually goes in the middle or the end of sentence, just before or after the verb and is also commonly used with the present perfect.
