Well, the problem is that very little information can be provided from the photos you supplied. I will give you my opinion on what I see.
In general, I think they are probably both legitimate Japanese swords.
The long sword or Katana fittings are mismatched. The tsuba (guard) and Tsuka (handle) are Type 3 late war Gunto, while the saya (scabbard) is not Gunto.
As a guess, I would say that there is a high probability that the blade is a non-traditionally made WWII era blade.
The short sword (wakizashi) presents the best likely hood of being a traditionally made blade.
This information can only be confirmed, denied or expounded upon by providing better photos.
You will need to remove the handles in order to see the Tangs.
The small bamboo pegs can be removed by pushing them out with a small punch, preferably brass. The handles should then come off with gentle persuasion.
Do not attempt to clean or remove rust or corrosion!!! This will cause more harm than good.
Here is a link to some tips which may help you provide better photos.
