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 past perfect tense is used to show that an action was completed before another action took place in the past. For example, "He had already left before I arrived." The present perfect tense is used to describe actions that happened at an unspecified time in the past or have relevance to the present. For example, "I have finished my homework."
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 present perfect tense of "exist" is "has/have existed."
The present perfect tense of "was" is "have been".

"Has finished" refers to a completed action in the past, while "has been finishing" typically implies an ongoing or continuous action that has recently been completed. "Has finished" suggests finality, while "has been finishing" suggests a process that has been happening over a period of time.
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 present perfect tense is used to describe actions that are completed at the present moment or have relevance to the present. For example, "I have finished my homework." Future perfect tense is used to describe actions that will be completed before a specific point in the future. For example, "By next week, I will have completed my project."
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.
"Do" is used with plural subjects and "does" is used with singular subjects in present simple tense. For example, "I do" and "He does."
Present perfect tense.
The present perfect tense of "hid" is "have/has hidden."
Perfect tenses indicate a completed action or state, often with a focus on the result or consequences. Simple tenses, on the other hand, focus on the action itself without indicating completion. For example, "She has eaten" (perfect tense) implies that the eating is complete, while "She eats" (simple tense) just describes the action of eating without indicating completion.
Actually, "have" is the present tense form for first and second person plural (I, you, we, they) while "has" is the present tense form for third person singular (he, she, it). For example: "I have, you have, we have, they have" versus "he has, she has, it has."
"Had been" is used to indicate the past perfect tense, showing an action that was completed before another point in the past. "Will have been" is used to talk about the future perfect tense, indicating an action that will be completed at some point in the future before another specified time.
