These are Confederate roses (Hibiscus mutabilis cv. versicolor) and the first five photos are of one flower, taken at 10:00, 12:30, 15:30 and 16:30 on 16 September 2024 and at 5:30 on the following morning. After such a color change from pure white in the morning to pink in the afternoon, this type of Confederate roses is named "sui fuyou," which translates into "drunken Confederate rose."
The sixth and the last ones are red and white marbled. Some Japanese apricot trees produce such colored flowers but (I believe that) a Confederate rose tree producing such flowers is quite unusual. White apricot trees don't exist but red ones produce white or red/white marbled flowers when they cannot produce enough anthocyanins to make flowers red. The same may apply to this hibiscus tree.
If you want to see peach, Japanese apricot, or lespedeza having white, pink/red or marble-colored flowers on a tree, read the following posts:
