No, the correct phrasing would be "When 'you' arrived, she had already left." By adding the comma after "arrived," the sentence is clearer and reads more smoothly.
The correct phrase is "arrived for her." In this case, "her" is the objective pronoun that should be used after the preposition "for."
When he arrived I was ready to go is correct
No, "Is she and you arrived at the airport on time" is not correct. It should be "Did she and you arrive at the airport on time?" or "Did she and you both arrive at the airport on time?" for proper subject-verb agreement.
The phrase "has already had' is correct.
as in "I just arrived from school" or " Why do you always just arrive whenever shcool is done?"
