Cleopatra is by far one of the most ever famous queens of all times in ancient Egypt. Her story of love and death is very famous and she ruled Egypt and made it quite powerful at the time.
Cleopatra was born in 69 B.C. in Alexandria. She was the third daughter in line to her father Ptolemy XII; she later had another sister and two younger brothers. Her younger brother Ptolemy XIII later reigned with her.
Cleopatra's story is one of the most famous ever.
Not only because of her great love, but because she was deeply in love of Egypt and she is classified by historians to be the last Pharoah of Egypt.
Cleopatra came to the throne after death of her two elder sisters and after death of her father whom was much hated by the Egyptian and had fled to Rome several years before.

I think the first sentence is flawed.
It should be 'Cleopatra is by far the one of the most ever famous queens ...'

I think even the following sounds strange.
Cleopatra's story is one of the most famous ever.
Do you write 'famous ever' in the sentence?
I am not sure.

There are problems throughout this passage. The first sentence is flawed in a number of ways, but your suggestion won't fix it since "the one of the most" is ungrammatical.

There is a basic problem with using "one of" and "by far" together. The two are not compatible. Also, "ever" is misplaced, "of all times" should be "of all time", and "ever ... of all time" is unnecessary repetition and contradicts the qualification "in ancient Egypt". This is one way to rephrase it:

"Cleopatra, queen of ancient Egypt, is one of the most famous queens ever / of all time."

"Cleopatra's story is one of the most famous ever" is OK, but feels chatty/conversational, and I'm not sure I'd use this construction in very formal writing.

I didn't write this article. I read it on a website. I was searching about Cleopatra.

You said "the one of the most' was ungrammatical.

On reflection, I would agree with you.

We say, for example, Tiger Woods is one of the most famous golfers of our generation.
