Reproduction of tables or figures from OA articles may be permitted. In this case it will state on the article that it is possible to use for commercial purposes. You must still:
Include the original figure or table
Identify the publisher as the original publisher
Give the proper attribution of authorship and citation details as acknowledgement
However, you cannot assume that this applies to all OA publications, and you must check the terms of conditions of any OA journal and article in question, to ensure that it is possible to use images even for commercial purposes.
