Q: "the door is 'open'." Why not 'opened'? = "the door is 'closed'." は 英語 (アメリカ) で何と言いますか?
A: "Open" is an adjective. We are describing the door when we say, "The door is open."
"Opened" is the past participle. We are describing what happens to the door, for example, when we say, "The door is opened by the door man."
"Closed" happens to be both the adjective and past participle. So we say, "The door is closed.", and, "The door was closed by the door man."

Q: If I say: "The door opened", does it suggest that the door could have been opened both by itself or by someone?
A: Literally speaking, it sounds like the door seemed to have opened by itself but it depends on the context. It doesn't completely preclude being opened by someone, but choosing not to imply any agent sounds like it could've opened on its own.

Other times it may just be because you want to emphasise the action of the door opening over who opened it.

Not so literally, this kind of sentence might also be used somewhat poetically just to describe a setting.

Here are some example sentences:

"I had to try the lock three times before the door finally opened."

"The door opened and five large men entered."

"While exploring the old house, the girl discovered a side door that opened to a beautiful courtyard."

Q: The door opened, and in came a little girl with a red ribbon on her hair. この表現は自然ですか?
A: So close!!!!

"...girl with a red ribbon in her hair."

If you're going to use the noun of hair, then it must be "in"
But if you really want to use "on" then the noun of head would work best.

"In her hair" vs "on her head"

With this sentence I think in her hair is best
