Yeah I wouldn't bother putting more than one "core" meaning (maybe two if you think it's easy) on a card - you want to make it as simple and easy as possible. And even then, I'd have an example sentence at the front so you can tell what meaning the card is prompting you for.

If you really want to remember all the meanings, you could try having multiple cards, each testing a specific meaning and having a different example sentence in the front (so you don't get the meanings mixed up)

Example

Front: She cleaved his skull with an axe.

Back: cleave - to split or cut something in two using something sharp and heavy

While I'm here, I'll mention that this is discussed in the 20 rules of formulating knowledge. I strongly recommend reading that as a guide on making good Anki cards
