They aren't refered to as 'banana magazine'.
People will laugh at you for saying that. Not to be rude.
But some hold 20, some 30.
When Armalite first produced the AR-15, the magazines were straight walled. This limited the capacity to 20 rounds, as the taper in the cartridge case would cause feeding problems. To counteract this, the "banana magazine" as you called it was produced. In USA conversation, this term is not generally used, but has been used in the media and some movies. 20 round magazines today are still straight walled.
I think you are talking about the STANAG magazine, which holds up to 20 rounds
The M16 rifle typically has a standard magazine that holds 30 rounds of 5.56x45mm NATO ammunition. However, there are also variations with different magazine capacities available, such as 20-round magazines. The number of bullets can vary depending on the specific model and configuration, but the 30-round magazine is the most common.

There are 20 and 30 round magazines. some even 10 rounds There is also a "BETA Mag" that holds 100 rounds. It uses to drums of ammo that attach underneath it. They are heavy and only used for mounted m16's or over watch duty.

The standard magazine capacity for the M16 rifle is typically 20 or 30 rounds, depending on the variant. The 20-round magazine is often used for precision shooting and is favored for its lower profile, while the 30-round magazine is more common for general use and combat situations. Both magazine types are designed to hold 5.56x45mm NATO cartridges, which are standard for the M16 platform.
The M249 is typically fed from a belt... 100 round "nutsacks" and 200 round plastic drums are often used. It can also be magazine fed from STANAG 4179 magazines (the type used in the M16 and several other rifles). Those can be whatever capacity they're manufactured for, but 30 rounds is typical.

Yes
The type of stoppage that occurs from not seating the magazine properly in an M16 is known as a "failure to feed." This happens when the bolt fails to pick up a round from the magazine, which can lead to the weapon being unable to fire. Ensuring the magazine is fully seated is essential for reliable operation.
It depends strictly on the magazine. Some magazines hold 10 rounds, some hold 30 or more.
