Then I'll throw the gender tit-bits into the pot, since it was you - I think? that was having trouble with connecting them to the cards. If you have a Lenormand with the playing card insets, it's easier to see.
When it's a court, usually when it means a person, it's a person the same gender as the court is. Once in a while, no, as Sylvie said, but usually you'll see some other cards indicating that (in the case of the Child, it's often a child of either gender, or a young woman). It may take a little practise, but do look at the playing card inset if you're trying to work out who a person is.
Sometimes the Whips can mean siblings - not often, but it has come up in my readings. As can the birds, though they can represent a couple as well, or sometimes - bullies or nosy people. Storks and Paths can sometimes represent two women in the same family or two women who are friends.
As a rule (there are exceptions, and you'll get to understand them in practise) if a person is being referred to by a NON court card, then red cards are men and boys, black cards are girls and women. USUALLY. Not always. The Moon is a red card, and often it refers to a woman if it's talking about a person. Again - often. When you're reading for somebody you'll get a better idea of the story, and be able to pick up more of it in the cards.
And something to take into consideration on the playing card side of things. Mme Lenormand didn't invent the cards that bear her name, but I think she was responsible for this innovation:
In normal playing card reading, almost all systems, Spades are the trouble suit. Not so in Lenormand. Clubs look like crosses, and in 18th century Catholic France...that's how she took them. That's why most of the Clubs cards in Lenormand deal with sacrifice, hardship, obligation, or commitment (hence the Ring being in Clubs).
People screw that one up a lot. But look at who the Courts are here - the Clouds is the Clubs King. Sometimes not a very nice man, or sometimes an older relative, often an ex-husband - someone with whom you have an obligation. And also, if the Clouds are near a person card, especially the dark side of them, they can indicate a smoker (trivia, but sometimes useful). In French Cartomancy, I take the right side of the Clouds to be dark, because in my really old Dondorf (same pattern deck) they are darker on the right - it's harder to tell in the FC.
The Clubs Queen is the Serpent, who also has a rather bad reputation from time to time. She's not always bad, but she's far more likely to be unpleasant than the Spades Queen, who's the Flowers. And the Lillies is the Spades King (notice how they're both associated with flowers), who is not usually unpleasant, either. Can be, depending on the surrounding cards, but that's true of any of them. But not by itself.
I think some people not taking into account that the playing card meanings don't involve 'elements', but instead involve 'qualities' in the Lenormand system is one of the reasons some readings get so schiz, so to speak - like somebody will see the Flowers and say 'oh, you'll have a really nice time but a vicious woman will do something to ruin it'. No, nothing there to indicate that - they're just being thrown by the Spades inset. The Lady card is the Ace of Spades - that doesn't mean 'bad'.
Anyway, most of that is from my personal experience. Your mileage may vary, of course, and likely it will. But it's some of what I've picked up over the years, and a starting point if you haven't got one.
