Recently my gran gave me her old Olympus OM-1 and OM10 cameras and a huge variety of old filters which I am unsure of how to use as this is really my first venture into analogue photography apart from as a child with my little barbie camera!! I would really appreciate if someone could tell me what some of these filters should be used for, with what kinds of film and In what sorts of situations. Here are some of them:

A Cokin coef +1 blue (80 c) a022
A Cokin dreams 3 a093
A Cokin coef +2 blue (80 a) 020
A Cokin coef +1/3 yellow a001
A hoyarex 701 diffraction 2x
A hoyarex 222 diffusier 2
A Cokin coef +1 orange a002
A hoyarex 326 star 6
A hoyarex 523 gradual t2
A hoyarex 031 sepia
A hoyarex 611 pl-linear
A hoyarex 121 soft spot
A hoyarex 216 fog half
A hoyarex 011 skylight 1b

Thanks very much if you can give me some insight
