Algebraic stucture, sure, but _algebra_, absolutely not.
An algebra is a module with a compatible multiplication which has an identity element. If I had a magma and you asked about my "algebra" I would be very confused about where you were seeing all the extra structure.

As someone else pointed out elsethread, the term seems to be overloaded in different branches of mathematics. https://en.wikipedia.org/wiki/Universal_algebra https://en.wikipedia.org/wiki/Universal_algebra: "Universal algebra (sometimes called general algebra) is the field of mathematics that studies algebraic structures themselves, not examples ("models") of algebraic structures. [...] In universal algebra, an algebra (or algebraic structure) is a set A together with a collection of operations on A."
