Indicator bulbs should be easy to do with battery in place, the dipped and main beam bulbs should also be easy enough to do shouldn't be any corrosion on the terminals in a sealed headlight. The sidelight bulbs can be tight and awkward to get out with your fingers, try a pair of long nosed pliers or regular pliers, grip the holder and wiggle it, should pull out then. Sometimes its just a case of brute force.
The fog light bulbs are again do-able just means squeezing ur hand in and feeling around.
