I can't remember exactly what posts the game has but if they are white faceted posts then yes the ones in the links should be the correct ones.

Pretty sure these were the skirts i used on the last Hankin game i did

Haven't used Yoppsicles on anything yet (might be using them in a Fathom I'm currently doing though), but if they are intended for old
school Bally/Stern then you shouldn't have any issues running them in Orbit 1 as the Hankin board set is essentially the same in how they
operate overall.
