Does anybody may find these images' sources?

Base +5

Judging that theyre all from pixiv, just copy the filename (minus the _p0 _p1 etc), go to some ransom image you favorited on pixiv, highlight the last numbers on the link, paste the filename over it, hit enter, and if it's still there, you'll find you sources. Either that or use saucenao.
