I have had great success adopting feral cats (albeit in the US) over the years. As Kelly says, some will take to you and some will not, so my advice would be to start befriending (feeding) them and see which ones will be approachable enough to bring home.
Another recommendation is that once you take in the cat, it should stay indoor. Some cats will complain at first but all the ones i have taken in (>25 over the years) got used to it and ended up being happy as indoor cats.
