* If you mean using "was" twice in a sentence: Yes, you can definitely use "was" twice in a sentence. For example:
* "He was happy, but he was also tired."
* "The cake was delicious, and the ice cream was too."
* If you mean using "two was" together as a phrase: This is grammatically incorrect. "Was" is a verb that requires a subject, and "two" is a number, not a subject.
If you're trying to express a specific idea, please rephrase your question and I can help you write a grammatically correct sentence.
