Read the EULA, yes you can as long as you did not make more than $100 000 revenue in the previous financial year. If you are asking I doubt you made them.

Yes you can according to their EULA, if your app makes $100,000 in revenue only then you are subject to purchase their license, although you will need google developer account to publish game on Play Store.
