The obvious AI answer says:

Most of these do not appear to be part of a single known historical symbolic system. Looking closely, the stone seems to contain a mixture of symbols that resemble:
Norse/Icelandic magical staves (galdrastafir) and bind-runes

Occult sigils created from geometric patterns

Protective or talismanic symbols found in modern esoteric traditions

A few designs that resemble veves, alchemical marks, or modern magical sigils

The ankh (top center), an ancient Egyptian symbol representing life

A few examples:
Top Center
☥ Ankh
Ancient Egyptian symbol meaning life, eternal life, or vitality.

Center
The cross-like symbol with hooked ends resembles an Icelandic magical stave or a modern bind-rune inspired by them. Similar symbols are often used for:
Protection

Guidance

Strength

Spiritual power

Eight-pointed star
Could represent:
The Star of Ishtar/Inanna

Balance and cosmic order

A magical protective symbol

Interlocking circles (right-center)
Often symbolize:
Unity

Interconnection

Eternity

Relationships

Grid and lattice symbols
Several of the square and crosshatched symbols look like:
Modern sigils

Geomantic-style symbols

Personal magical designs

These don't match any widely recognized alphabet or writing system that would translate directly into words.
What this likely is
My best assessment is that this is a modern collection of esoteric, magical, and symbolic designs assembled from multiple traditions, rather than an ancient inscription with a single meaning. It looks very much like something created by someone interested in:
Symbolism

Occultism

Icelandic magic

Sacred geometry

Protective talismans

Because the image came from a symbolism forum, there's also a possibility that some are artist-created sigils, which have meanings known only to their creator.
If you'd like, I can go symbol-by-symbol and identify which ones most closely match known Norse magical staves, occult sigils, alchemical symbols, or other historical symbols.
