In certain Pentecostal and Charismatic circles, Isaiah 11 describes the seven spirits (or seven-fold spirit) of God from revelation.
The first one is "the Spirit of the LORD", then the Spirit of wisfom, etc. It is interesting to note that this Catholic source cited leaves off the first, and inserts "piety".
As for the question, referring to Proverbs, first let's differentiate knowledge and understanding.
Proverbs 15:14 and Proverbs 18:15 both say that the heart/mind with understanding seeks knowledge. Proverbs 14:6 says that knowledge is easy for him who has understanding.
Elsewhere, in Ps 119:34, David aays, give me understanding that I might keep your law.
Thus, knowledge of the law, specifically, what it says, is simply knowledge. David had the law, the knowledge, but he was seeking the understanding of why such as such was so. The principle is then, if you know what the law says, you can obey by rote. But, as you gain understanding of the Law, that all the Law really hangs on love, say, the knowledge of the law becomes easy.
But, this is not limited to the law, but everything. As abivr, if someone has understanding, they will generally seek out knowledge. If you have general understanding of automobiles, when you encounter a new car, say a hybrid electric, the normal tendency would be to seek out knowledge. Or, if it is computers, if you have general understanding, how the parts interoperate, you become more interested in the individual parts thrmselves.
In this way, knowledge is simply the facts, data, where understanding is how they "work". But, this understanding of how they work is not limited to the knowledge itself, and the presence of knowledge without understanding leads one to investigation.
Then, we have wisdom, which is different than both. The fear of the Lord is the beginning of wisdom, and the fear of the Lord is to hate evil, so wisdom incorporates the hating of evil.
It doesn't take much 'wisdom', or sense, to begin to realize that many people have both knowledge and understanding, yet they lack the sense of what's a good idea. This is wisdom, and involves action and restraint. By knowledge and understanding, you could make the largest ski ramp in the world, capable of launching a skier (victim) a half a mile into the air... But, by wisdom, a life is preserved (Ecclesiasties 7:12).
You can also have wisfom without either of the other two, but they work well together.
Not in your question is counsel and might. The first might be refered to as the ability to convey the information to another, or to have it conveyed to you. A man might have knowledge (all the pieces), understanding (how they work together), and wisdom (when and how to use them), but he may not be able to pass that onto anyone else. He has thrm, but cannot counsel, or share it (teach). May who are very good at what they do make lousy teachers, no counsel. And, might is the ability to perform. You can know how it all works, and be Able to teach, but might is the actual power to implement it.
Various examples of combinations could be given. Many have some in greater manifestation than others. They work the best in combination, but each is something unique.
The other two, the spirit of the LORD and the fear of the LORD, will wait for somewhere else.
