(2) is grammatically the most correct option. (1) is incorrect because pronoun agreement is violated here. Two nouns are joined by using 'or'. Hence, a singular pronoun will be used to point out to the nouns. (3) is incorrect because of usage of 'there'. (4) is incorrect because 'them' is an objective pronoun and it's usage is wrong in the sentence. (5) is incorrect because pronoun 'these' is used to refer to plural nouns while the subjects in the sentence are singular.
