If I'm playing as Popo (ice climbers), any hits on Nana will not affect my percentage. Does that mean that Nana has her own percentage score? If she does, is there a way to tell what it is?
Does Nana (from the Ice Climbers) have her own percentage score

During Ice Climbers' up special (referred to as "up B" from here), the hitbox is around Nana's head, and only when she is flying upwards. Popo has no hitbox during the attack.
Because of these properties, it is quite risky to use it as a method of hitting the opponent while they are edge hogging. As you are almost guaranteed to lose Nana if you try, I highly recommend considering the side special instead in most such situations. Side B gains upwards momentum when you mash the special button during the animation, has a continuous hitbox and it can be used to go very high. However, if the opponent is not edge hogging, up B is often a far safer choice as it allows you to grab the ledge faster.
It is also fairly difficult to land a hit after an up throw using up B, as landing it is dependent on the opponent's damage and whether they affect the trajectory (DI) or not. What I see most top-level Ice Climbers players use instead is up air, as it can lead to juggles and keeps the opponent in a bad position. It is worth noting that up B's hitbox is surprisingly strong, and might lead into an early KO, though. You can slightly move Nana while doing up B, which can help with hitting the opponent.
The most common situation where up B can be considered a better attack than either up air or side B is when you are recovering, are almost directly below the ledge, the opponent is following you off-stage, is directly above you at an appropriate range, and you know that they will try to attack. Because of the invincibility and priority, up B will most likely hit them and possibly cause a stage spike, and Popo or even both Climbers will recover safely, depending on the distance.
In a nutshell, it is often better to consider other options before using up B offensively, but it has some uses.
There is no way to directly control the secondary Ice Climber, although some of the alternate costumes will feature Nana as the lead Ice Climber, including the white costume that you mentioned. Popo will always appear to be the lead in the character portrait, but Nana is actually the lead for every other costume (shown second, fourth, and sixth below):
As the Ice Climbers character, the player controls only the lead Ice Climber, while the secondary Ice Climber mimics the lead. It is possible to grab a different item with each Ice Climber, and possible to de-sync the two Ice Climbers in order to chain attacks or grabs together in rapid succession.
The best way to get the secondary Ice Climber unstuck is to reunite the two of them so that they can move together again.
Best Answer
Yes, Nana has her own percentage score. As it goes up, she'll become easier and easier for your opponents to kill, just like your own.
No, you can't tell what it is. Just pay close attention. If you both get hit by the same attack, judge the difference in distance between how far you went and how far she went and you can estimate based off that.
