Can I take ibuprofen for swollen muscles while on lansoprazole for acid reflux and propranolol for anxiety?

Yes, but. In fact, the Lansoprazole can provide protection to the lining of your stomach from the injurious effect of the ibuprofen. Be careful with the Ibuprofen and the propranalol, it may cause a diminution of the propranalols antihypertensive effect.
