1. I have been late for school more than ten times when I was a middle school student.
2. I have not broken windows before.
3. I have never used a cell phone in class.
4. I have played ball in my classroom before.
5. I have ever played ball in my classroom.
(Are they all grammatical? Is #5 a corect expression?)
#5. no. I have never...is fine and you might hear the question: "Have you ever..." but not as it is. You could say: "I have always..."

Let's analyze each sentence to determine their grammaticality and correctness:
1. "I have been late for school more than ten times when I was a middle school student."
This sentence is grammatically correct. It uses the present perfect tense ("have been late") to indicate a past action that has relevance to the present. The use of "more than ten times" specifies the frequency of being late and "when I was a middle school student" provides the time frame.
2. "I have not broken windows before."
This sentence is grammatically correct. It uses the present perfect tense ("have not broken") to indicate a past action that hasn't occurred up until now. The word "before" emphasizes that breaking windows has never been done previously.
3. "I have never used a cell phone in class."
This sentence is grammatically correct. It employs the present perfect tense ("have never used") to express an action that hasn't happened in the past up until now. The phrase "in class" specifies the context in which the action of using a cell phone has never taken place.
4. "I have played ball in my classroom before."
This sentence is grammatically correct. It uses the present perfect tense ("have played") to indicate a past action, and "before" indicates that playing ball in the classroom has previously occurred.
5. "I have ever played ball in my classroom."
This sentence is not grammatically correct. The word "ever" is unnecessary in this sentence because the present perfect tense ("have played") already implies that the action occurred at some indefinite time in the past. A correct construction would be "I have played ball in my classroom."
