This could be achieved using R1C1 notation. Function refering R[0]C[0] takes the value from current cell. Number inside [] indicates up or down position cell from current cell. 0 - current cell.

For reference

{
    dataType: "custom",
    from: "AND(ISNUMBER(R[0]C[0]),LEN(R[0]C[0])<6)",
    type: "warning",
    allowNulls: true,
    titleTemplate: "Invalid Item",
    messageTemplate: "Value must be a number and 5 characters or less"
}

 

Hope this helps.
