The kabbalistic squares were taken by the Jews and added into the kabbalah
They aren't part of the jewish kikebalah. They are used by gentile ceremonial magicians who dabble in jew magick, as the first modern mention of them comes from Agrippa and they were later used by the Golden Dawn and others. Jewish rabbis who teach the kikebalah have no idea what they are and never mention them.

but one doubt I have is, do their corrupted versions have any spiritual benefit to them ? Like, they use the numbers along with gematria to get specific Hebrew letters, would a Jew with access to this tool have the ability to use real magic ?
If the answer is yes, can they bring energies from the 7 planets of astrology to use it as we do with squares ?
It's just some complex nonsense, they use a planetary square to create the sigils of the supposed spirit and angel of a planet using the gematria association of the letters of their names and engrave them in the specific metal associated with that planet to create a planetary talisman and wear it.
All these ceremonial magickians have a medieval worldview where everything is ruled by spirits, and they think that to use the energies of a planet you have to invoke the spirit of that planet by engraving its sigil in a talisman and wearing it. That's it, they think that wearing this talisman will bring the effects of that planet in their lives, for example a Venus talisman will make them attractive to women.
It differs from ours, as we invoke the impersonal energies of a planet by these vibrations, and we don't fall into medieval superstitions believing that everything is ruled by spirits. That's why I doubt it works, and even if it does it will be much weaker than the SS method.
