@Super,
A rule of thumb (or variations of this) for LEDs in series:
Number of LEDs that can be used in series = Supply Voltage divided by 0.8
This is assuming standard LEDs (non-high brightness).
Yes, a larger resistor will make the LEDs shine darker.
If you have multiple LEDs in series, the same applies. A larger resistor in series with those LEDs will make the LEDs darker. The LEDs in series will always have the same brightness and you can't control them independently.
I recommend LEDs in parallel with one resistor each. That allows you to control each brightness independently and you can have as many LEDs you want. Note that more LEDs will make the battery run down faster!
