Is any update for Android 11 for one plus 5?
No, there will be no further updates to the OnePlus 5 and 5T, as mentioned here:
The OnePlus 5 has already reached end-of-life.
No further updates for oneplus 5 & 5T as it's final update is OS 10.0.1
Samsung is better than one plus, they are providing time to time updates and also provides latest updates features and OS.
Next time I will never buy one plus product.
