Yes, "friend" for both genders. However using "boyfriend" will always mean a male partner (for women and men), and "girlfriend" means a female partner for men, and a close friend, like a sister, for women. Eg. She: "I'm meeting with my girlfriend for lunch". = she's meeting with a close female friend. When a man says this, it means his actual girlfriend. To make it clear they are friends but there is no boy/girlfriend relationship, you just use "male friend" or "female friend". We also use "lady friend" to indicate the female friend of a man may or may not be a girlfriend.

u are right

boys can have a lot of girl friends,but if he got lots of girlfriends,people would call him player.:p

Hi... yes in English it is the same word for boy or girl... If you want to mention female or male you need to add girl friend or boy friend...

Yes, that is correct
