The present perfect tense is used when there is a connection with the past and the present. It's used to denote experience, change and a continuing situation.
The past tense, on the other hand, is simple in that it only talks about actions that have happened in the past (and it MUST be used whenever you specify WHEN a certain action took place).
Present perfect progressive and present perfect continuous refer to the same tense and are often used interchangeably. Both tenses indicate an action that started in the past and is ongoing or has just been completed. The choice between "progressive" and "continuous" is mainly a matter of dialect or personal preference.
"Has finished" is the present perfect tense (third person). "Has beenfinishing" is the present perfect progressive tense (also third person).
The difference in meaning is that the action stated by a present perfect tense may have been completed in the last second of time before the present, while the past perfect implies completion at a substantially earlier time. The formal difference is that the present perfect is formed from the present tense of "have", used as an auxiliary verb, combined with the past participle of the principal verb. For the past perfect tense, the past tense of "have" as the auxiliary verb is combined with the past participle of the principal verb.
The past perfect tense shows an action in the distant past eg. I had eaten cereal for breakfast yesterday. The present perfect tense shows an action in the recent past, eg. I have just eaten my lunch.
The present perfect tense is used when there is a connection with the past and the present. It is used to depict change, experience and a continuing situation. The future perfect tense, however, is used to talk about the past in the future.
The past participle is used for forming the perfect tenses and passive voice, often ending in -ed or -en, like "bought" or "taken." The present participle ends in -ing and is used to form the progressive tenses or as a gerund, like "buying" or "taking."
There are two forms of the present perfect tense: simple present perfect (I have eaten) and progressive present perfect (I have been eating). Both forms use "have" or "has" with the past participle of the main verb to indicate an action that started in the past and has relevance to the present.
