Answer 1

without a picture no one can really tell you. it just might be peppers. you say you didn't put them there, but sometimes seeds make their way into the potting soil. they could have also fallen in there when you were seeding a pepper or even if you use compost.  

Answer 2

Sounds more like eggplant blooms..
