Will all the bulbs have the same brightness in a series circuit, regardless of how many there are? Does the number of bulbs affect their brightness?

IF all the bulbs are identical bulbs . . . . .
All the bulbs in series have the same brightness, and that brightness depends on how many there are. More bulbs ... all are equally less bright. Fewer bulbs ... all are equally brighter.
If the bulbs are not all identical, then it depends on what each one is, which one was removed, etc., and it can get complicated.

In a series circuit with identical bulbs, all bulbs will have the same brightness, but adding more bulbs will decrease their overall brightness. Fewer bulbs will result in increased brightness as they receive more current from the same voltage. If the bulbs are different, the brightness will vary based on each bulb's resistance.
