The verbs in these sentences are in the present perfect tense, which is used to describe actions that have been completed or are still relevant in the present. The present perfect tense is formed by using the auxiliary verb have and the past participle of the main verb. For regular verbs, the past participle is the same as the past tense form, which usually ends with -ed. For irregular verbs, the past participle can have different forms, such as left, read, gone, etc. You can find a list of irregular verbs here: https://www.ef.com/wwen/english-resources/english-grammar/irregular-verbs/
