I'm not an expert either but I wondered if the yellow ones that R Han posted might be golden chanterelles? In which case they would be edible.
For both of the ID questions, is there a mycology club in your area?
Local knowledge is invaluable when it comes to mushrooms. Lots of lookalikes out there so getting advice from someone who knows what species are found in your area is really necessary. Club members will know that sort of thing and often are keen to share that knowledge as long as you don't expect them to show you all their secret shrooming spots. Another option if you have a university nearby is to look in the botany department, I had a prof in university who was willing to help people identify shrooms. The payback for him was that it increased his understanding of local biodiversity and distribution.
