I think the necklace in the first and second photo looks fake. The pearls are extremely uniform, have no overtones and look flattened near the drill holes. But you can try rubbing the pearls gently agains each other-- do they slide smoothly? If so they are probably fake. Real pearls would be a bit gritty when rubbed together.

You can perform the same test on the second strand. For us to be able to have a better idea of what it is, we need more photos-- against a white background is best (like a paper towel), including some close-ups of several pearls, any blemishes, some shots of the drill holes, closeups of the clasp and see if there is any mark on the clasp (14K, 925, etc.)
