The leaves, flower and fruit all look like my pepper plants, although mine are a diffrent variety (thai red fogo) so they are much more slender. Wait until they're ripe and cut one open, a smell of the inside and the little white pepper seeds alone should tell you that they are indeed peppers. I would just eat one and see how it tastes. I don't think it could be anything dangerous or inedible, but you might burn your ass off if they turn out to be habaneros
