The ones where I can see the gill-like surface are Chanterelles, not my local species I think, but you can tell mainly by the false gills or folds - a spore-producing surface that you can peel off the rest of the mushroom.
The one with its cap facing the camera probably is a Chanterelle, but can't tell for sure from that angle.

There are other false gill/fold bearing mushrooms, some you would probably not want to eat, but they have other features that distinguish them.

Please also note that if you are new to distinguishing true gills from folds, Hygrophoropsis aurantiaca
looks similar to a chanterelle, but has true gills and grow on wood. True Chanterelles grow from the ground.
