It's just a smiley face with text. That can be a flirt but its hard say if the guy really likes you. He may like you cause he seems to be flirting:)
Hi good evening. A guy friend keep sending me the blush smiley faces, fifth on top row with the small smile and with eyebrows. Does that mean he likes me?
It kind of depends whether he flirts much, try to notice he's other actions that might mean he likes you. Dont judge it just on that.... But if other things like that are happening, then he probably does like you
