The subject "Each of the team members" is singular, meaning the verb should be singular as well. The correct verb form to use with "Each" is "has," not "have." The phrase "their best effort" should also be singular to match "each." Therefore, the correct phrase is "has given their best effort," which is grammatically correct. "have given their best efforts" uses "have," which doesn't agree with the singular subject "Each." "had given their best" uses the past perfect tense ("had given"), which is unnecessary in this context. "gave their best" uses the simple past tense, which isn't the right tense for this sentence.
