Welcome shinsuko.
I can be fairly certain they are tropical species or hybrids from near the equator in the Western hemisphere, probably Mexico.
Many of these Pinguicula, especially when grown in lower than optimal light levels become lest distinct. They lose some of the distinguishing morphological characteristics of their non-reproductive parts. The flowers usually are the part of the plant less affected by changes in its environment - so they are usually the best way to identify Pinguicula, especially in these situations. However, some species respond to less-than-optimal conditions by refusing to bloom.
Your best chance of identifying these plants is to learn how to provide them a better environment, then waiting for them to bloom and/or grow to look more distinctive.
Under the circumstances, with the plants looking light-starved and somewhat etiolated, I would guess that the first one might be P. moranensis or derived from a P. moranensis hybrid, and the second one may be P. agnata, P. esseriana, or even P. ehlersiae. But these are only guesses, especially since neither plant is in bloom, right now.
