Yes, low oil level can cause low pressure.
It's an oil pressure warning light, not an oil level warning light. If your oil level gets low enough to cause a drop in oil pressure, you're basically running dry.Take it to a mechanic.
Adding too much oil will cause your engine to burn off the excessive oil which causes a lot of carbon buildup in your engine and a lot of blue smoke out your tailpipe. If the oil level is high enough, it can contact the crankshaft and foam up. If the oil foams it can damage the engine.
It is normal for the pressure to drop. It depends what you mean by "very low". Check the oil level and the condition of the oil and filter. The oil and filter may need changing.

Do not overfill the engine. As the crankshaft spins around, it can whip the oil into foam if the level is too high. This, in turn, can cause a drop in oil pressure and loss of lubrication to critical engine parts. Also, too much oil may cause leaks as the extra oil is forced past seals and gaskets. Drain it out immediately.
Yes
No, it would cause the "low oil" light to come on.
Low oil level? Oil may "slosh" forward on hard stop causing a temporary drop in oil pressure
First thing that you should do is check and see what your oil level is. If you have over filled the the vehicle with oil this will cause the engine to knock, and cause further damage to your engine. Make sure that vehicle is on level ground and check the oil dip stick. The oil lubricating the dip stick should not be beyond the full mark. If it is remove the drain plug from the oil pan to bring the oil to the proper level.
your oil pump is bad
A low oil level can cause the oil light to blink on a 1995 Honda Prelude. A faulty sensor can also cause this.
