>>4449987>>4449988A lens can be one or the other or both. A macro lens is one that allows you to focus closely, resulting in your subject taking up more of the frame and being more magnified.
A telephoto is one with a long focal length, or a higher number before the mm (which if you didn't know stands for millimetres). At what point a lens becomes telephoto (ignoring the technical definition) can vary slightly from person to person, and also changes based on the sensor size of your camera. Generally speaking it's anything longer than around the diagonal dimension of the sensor, so longer than about 50mm for full frame, longer than 35mm for APS-C, longer than 25mm for a four thirds camera, etc.
Combining these two, a longer more telephoto lens that is also a macro lens will allow you to get high magnification on your subject while also being further away from it, because it will be more "zoomed in". For simplicity's sake that's what the focal length means, a longer focal length gives you a tighter field of view that is more zoomed in. Double the focal length and you're basically cropping a quarter off each side of the image, or you can double your distance from your subject and get essentially the same photo (not exactly, but again we're simplifying things).
