I have went to the store and buyed some apples. The children has eaten well.

Corrected, explained, understood

I have gone to the store and bought some apples. The children have eaten well.

Poli explains why

"went" → "gone": with "have", you need the past participle, not the simple past. "buyed" → "bought": "buy" is an irregular verb. "has" → "have": "children" is plural, so the verb agrees in the plural.
