The phrase 'Each of us' is grammatically singular because 'each' is a singular pronoun. Therefore, it takes a singular verb form. The correct verb to use is 'has' (B), not 'have' (A). Although 'us' is plural, the subject is 'each,' which is singular, so the verb agrees with 'each.' The phrase 'Each of us has eaten our meal' is correct and commonly accepted. The use of 'have' would be grammatically incorrect in formal English in this context.

The subject 'Teachers as well as headmaster' is treated as plural, so the plural verb 'are' is correct. 'Is' and 'was' are singular verbs, and 'have' is not appropriate here.
