Aside from proficiency, there are exactly three different types of bonuses: circumstance, status, and item. Conversely, penalties have types, too, now, and there are the same three types as for bonuses. Bonuses of the same type do not stack, and penalties of the same type of not stack (you only suffer the worst one). You can however have both a bonus and a penalty of the same type. In addition, there can be a few untyped penalties, that are always added it, such as the penalty for taking multiple attacks on your turn, or for shooting beyond the first range increment of your weapon.
That's it. No other types of bonuses or penalties are to be expected.
