No other tree looks like a conifer.
The others look all the same and I don't know what they are. See if anyone else does. If not prick out a couple into separate pots and discard the rest unless you want loads all the same. More will germinate, trees germinate at vastly different rates.
If nothing else happens stick the pots in plastic bags in the fridge for a few weeks and see what happens after that.
