Description of a picture.

In this picture there are six people. They like are teens and they are in a class. Only two of them are boys. In the background there are 3 girls, one of them is sitting. The girl is sitting on a red chair, she is reading or holding a book, she has curly hairs, her legs are crossed. In front of her is a study table. She is wearing a grey shirt, a red tie, slim dark jeans, and a pair of white all-star shoes. Next to her, there are two girls: in the center of the background, there is a girl wearing a blue sleeveless t-shirt and jeans and the other is wearing a denim blouse, a pink t-shirt, a red belt, jeans, and red shoes like a ballet shoes. Probably they are explaining something about Math because behind them is a board and covered in mathematical equations. In the right hand corner there is a potted plant vase, I think is fake plant. And the other people are sitting and watching, in the foreground of the picture.

A few doubt:
*They like are teens or they like are teenagers? What is better?
*In ‘Only two of them are boys/male’.. Can I replace ‘boys’ to ‘men’ ?
*Blouse for women? and Jacket for men? is correct?
*Which is correct? ‘Probably they are explaining.. ‘ or ‘They are probably explaining..’ ?
*Potplant or potted?

Note: I can't attached the image, but I hope you all understand =)

Thanks in advance.
