Open access means that you (or your institution) do not have to pay to read the publication. It does not mean public domain. The copyright for the content including figures is with the authors and/or publisher. Therefore you need to get permission to reuse figures. - See also:
Dear Parisa Ghasemiyeh . Yes. The best way to have permission to reproduce a figure is using RightsLink. Most publishers use this service. If the publisher of the figure you wish to reproduce does not use RightsLink, you can request permissions directly from the publisher.

The answer is in the affirmative YES in line with Profs Aref Wazwaz Wolfgang R. Dick . Permission for usage of published figures, even in open access journals, is required to avoid copyright infringement and avoidable plagiarism. Hope this helps.
