The vast majority of these Power Armour suits are leveled

Hope this helps in some way

Updated it with all the locations I could: Hope this helps people find some power armour

Just a small minor recommendation... include the type of Power Armor at each location if known.

When you say they are "leveled" what do you mean? Is it better to leave suits alone until you reach higher levels etc?
