Grammar explanation
Time up to a point in the past
We use the past perfect simple (had + past participle) to talk about time up to a certain point in the past.
She'd published her first poem by the time she was eight.
We'd finished all the water before we were halfway up the mountain.
Had the parcel arrived when you called yesterday?
Past perfect for the earlier of two past actions
We can use the past perfect to show the order of two past events. The past perfect shows the earlier action and the past simple shows the later action.
When the police arrived, the thief had escaped.
It doesn't matter in which order we say the two events. The following sentence has the same meaning.
The thief had escaped when the police arrived.
Note that if there's only a single event, we don't use the past perfect, even if it happened a long time ago.
The Romans spoke Latin. (NOT
The Romans had spoken Latin.)
Past perfect after before
We can also use before + past perfect to show that an action was not done or was incomplete when the past simple action happened.
They left before I'd spoken to them.
Sadly, the author died before he'd finished the series.
Adverbs
We often use the adverbs already (= 'before the specified time'), still (= as previously), just (= 'a very short time before the specified time'), ever (= 'at any time before the specified time') or never (= 'at no time before the specified time') with the past perfect.
I called his office but he'd already left.
It still hadn't rained at the beginning of May.
I went to visit her when she'd just moved to Berlin.
It was the most beautiful photo I'd ever seen.
Had you ever visited London when you moved there?
I'd never met anyone from California before I met Jim.

Hello kingson,
Good, I'm glad. The grammar in this sentence is the same as the other one you asked about earlier. There is a very slight emphasis on 'you' finishing the work, but basically 'when you have finished the work' is another way of saying 'when the work is finished' (or 'has been finished').

Hello Shreya,
The sentence does not look fully grammatical to me. In particular, I can't see what it refers to in the middle of the sentence.
Perfect forms are highly dependent on context and it's hard to comment on the use of the past perfect without knowing how the events in a particular sentence fit into the broader context of other past events as described in the rest of the text. It could be that had seen is used here because it is part of a reported speech construction, with the direct speech being 'limiting visitor numbers saw...,' but I can't be sure from just the decontextualised sentence.

Hi kingson,
Re: question 2, the first sentence is correct, and the second one is not. Religious or metaphorical rebirths aside, we are born only once, and it's always in a past time. I can't think of any situation where the present perfect would be used with 'to be born'.
As for your other questions, please remember that while we try to be as helpful as we can with your questions about sentences you have written or found, we just can't explain everything. It just takes too much of the limited time we have for responding to comments. But I will give you very brief answers. For the first situation, you should say 'had taken' or 'took' and not 'has taken', and 'when he left home'. The past perfect isn't correct in the general context you describe in your third question.
All the best,
