Dos amigos y yo fuimos al Machu Picchu el verano pasado.

First of all, the preterite tense is one of two simple past tenses. It is used to describe actions that took place or were completed at a certain point in the past. The verb ir is irregular, so you must learn by heart conjugations of this verb. Thus, fuimos is the conjugation of the verb ir that matches the first person plural in the preterite tense. Finally:

Two friends and I went to Machu Picchu last summer.

Las vacaciones fueron maravillosas.

This sentence stands for the third person plural because vacaciones is a plural noun. Therefore, we must choose the conjugation of the verb ser that matches the third person plural in the preterite. This conjugation is fueron. Keep in mind that both the verb ser and ir have the same conjugations in the preterite. Finally:

The holidays were wonderful.

Yo fui al Parque Nacional del Manu también.

This sentence stands for the first person singular yo that means I in English. Therefore, the conjugation of the verb ir for the first person singular is fui. On the other hand, Parque Nacional means National Park. Finally, we can translate this sentence into English as follows:

I went to the Manu National Park as well.

La gente fue muy simpática

This sentence stands for the third person singular because gente is a feminine singular noun. On the other hand, the matching definite article is la (feminine singular form). Therefore, we must choose the conjugation of the verb ser that matches the third person singular in the preterite. This conjugation is fue. Finally, the translation is:

The people were very nice
