I’m writing an image class for a game I’m working on and some images I need rendered with different filters than others, is there a way to save OpenGL filter (GL_LINEAR, GL_NEAREST etc.) in a variable?

Well of course it is possible. But you can use any value you like, as long as you use the right token when doing the call to
glTexParameterifor actually setting the filter before commencing drawing with the texture in question. In later versions of OpenGL you can also use sampler objects to encapsulate a set of filtering settings.
