Grammar explanation
We often use just, yet, still and already with the present perfect because they are related to the present moment. This page focuses on the meaning and use of these words when they are used with the present perfect.
just
Just used with the present perfect means 'a short time before'.
I've just seen Susan coming out of the cinema.
Mike's just called. Can you ring him back, please?
Have you just taken my pen?!
Just comes between the auxiliary verb (have/has) and the past participle.
yet
Yet used with the present perfect means 'at any time up to now'. We use it to emphasise that we expect something to happen soon. Yet (in this context) is only used in negative sentences and questions.
Have you finished your homework yet?
I haven't finished it yet. I'll do it after dinner.
A. Where's Sam? B: He hasn't arrived yet.
Yet comes at the end of the sentence or question.
still
Still used with the present perfect means that something hasn't happened. We use it to emphasise that we expected the thing to happen earlier. Still (in this context) is only used in negative sentences.
I've been waiting for an hour and the bus still hasn't come.
They promised me that report yesterday but they still haven't finished it.
She still hasn't replied to my email. Maybe she's on holiday.
Still comes between the subject (the bus, they, etc.) and auxiliary verb (haven't/hasn't).
already
Already used with the present perfect means 'before now'. We use it to emphasise that something happened before something else or earlier than expected.
I've already spent my salary and it's two weeks before payday.
He wanted to see Sudden Risk but I've already seen it.
The train's left already!
Already can come between the auxiliary and the main verb or at the end of the clause.

Hello Piglet,
It's fine to use already with the present. For example:

Hello Piglet,
It's fine to use already with the present simple like that.
However, generally we do not use the present perfect with verbs relating to knowledge (think, remember, know etc) or to senses (see, feel, smell etc). The exception to this is when we are talking about a defined time up to the present:

Hello again Piglet,
I'm sorry if my reply was not clear. I meant that we do not generally use the present perfect with verbs relating to knowledge when we use already. I assumed this was clear from the context of the original question but should have made it explicit to avoid confusion.
The examples you quote are fine. Obviously, they do not use the adverb already.

Hello again Piglet,
These are not rules so much as tendencies - a useful rule of thumb, but not a fixed grammatical rule.
It is possible to use stative verbs with the present perfect and already in certain contexts. For example:
Note that 'see' in your example is not a stative verb. It's used in this context as a substitute for 'watch', which is dynamic.

Hi IsabelTim_123,
Adding yet in the sentences adds a bit of extra meaning. It means that the speaker has some expectation that the action should have happened by now, or will happen soon. For example, I have not finished my proposal yet suggests that he/she might finish it sometime soon. Without yet, the sentence is just stating that the proposal isn't finished. Has your passport arrived yet? suggests that I expected it to have already arrived. If it's very late, for example, you could say this.
About your second question, the two sentences mean the same thing! But the first version (be/have + yet to do something) is more formal in style.
Best wishes,
