You cannot connect them in series, to generate 10V, if that's what you want to know.
You may or may not be able to connect them in parallel, depending on specifics of the implementation.

Note that the A rating is "max power deliverable" -- power supplies do not "push" amps into circuits; circuits "draw" amps, and if they try to "draw" more amps than the rating, something will go "squish." (That's a technical term :-)
