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.

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.
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."
