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
The form 'had been learning' is a past perfect continuous. There are different possible meanings, but in general it describes actions or events which started before a reference point in the past and which were still happening up to that time. In theory, all of the possible uses on the Continuous aspect page also apply here.
Imagine that our friend Nancy took a Spanish language exam last week and got a high mark. If we didn't know she was a student of Spanish, we might say something like that sentence: 'I don't know how long she had been learning Spanish'.
Does that make sense?

Hello kingson,
The past perfect requires a second past time reference, but in your sentence you have only a present time reference (I do not know). Therefore, the past perfect is not possible here. You could use a present perfect or a past simple form:
The first sentence (has lost) tells us that the business still exists and is still losing money.
The second sentence (lost) tells us that you are talking only about a past event, so the business either no longer exists, or is no longer losing money, or else you simply have no information about more recent results.

Hello kingson,
The past perfect needs to reference a second action in the past as it shows an action before another action in the past. It's not enough to simply have a past time reference; you need a second action (state/situation etc).
The past continuous needs to be placed in the past by a past time reference (a time reference, for example). This may be explicitly stated or implicit in the context.

Hello again kingson,
My apologies. I must have misread your question as I thought you were asking about the past continuous, not the past perfect continuous.
Perfect forms always refer backwards. They are retrospective in that sense. Thus, the present perfect looks back from the present, the future perfect looks back from a point in the future and the past perfect looks back from a point in the past towards some time or event further in the past.
This means that there must be a second past time reference when using the past perfect. This could be an action or a state, or simply a past time such as a date. It could be explicitly stated or implicit in the context, but it must be understood.
All of this is true of both the simple and continuous forms of the past perfect. Both require a second past time reference point.

Hello kingson
I don't see any past time reference in that sentence. Presumably, this would have been stated in the context, e.g. it might have been mentioned in the previous sentence or two.
