We can and do. Lagrange point 1 is between the Earth and Sun and has the [Solar and Heliospheric Observatory](https://www.nasa.gov/mission_pages/soho/index.html) parked there. L2, on the opposite side of the Earth, has the [Gaia satellite](https://sci.esa.int/web/gaia) parked there. The other points are much further away and I’m not sure if we use them.
