However, the spirit of the law is that you are free to use your own work several times as long as you clearly state that it is not the first time you present (this is not required if you both retain all the rights and no originality expected) it and that the previous publications are such and such.
To be on the safe side, write to the editors and request a permission to reprint (it is automatic unless the editor is an evil villain having personal grudge against you).
I am a bit "fuzzy" about how not to plagiarize myself in my thesis (I have had no problem regarding my journal publications).
(* In all publications mentioned I am the first -but not sole- author.) Even if your department does not allow a "stapler" thesis, it is entirely reasonable to expect that you should be able to freely use this material in a thesis.
Also, when you reuse figures, I'd include the "reprinted with permission" tag.
Finally, ask your advisor or other members of your department for guidance!
However anyone trying to accuse you of using your own work without his permission will make such a fool of himself in the scientific world that his reputation there will plummet to negative infinity, so I don't think the chances of trouble are above those that some crank will accuse you of plagiarizing his work or that the outcome of the accusation, if it occurs, will be essentially different.
The papers you have published and that my be under review in a journal require permission to rproduce.
Example: Jones (2017) emphasised that citations in the text should be consistent.
If a source has three or more authors, the name of the first author should be given, followed by the phrase "et al." Examples It was emphasised that citations in a text should be consistent (Jones et al., 2017). (2017) empahsised that citations in a text should be consistent.
