A Couple Mysterious Old Coins From A Pick Box

Ok I have three coins I am trying to figure out, and I don't quite have enough information so google isn't helping. I guess searching a portion of a word doesn't always yield a result. This first image is the hardest. Not much can be seen. It looks like a triangle in the middle with something at each corner and a crown over the top. Also, there might be a 4 at the bottom of the triangle. At the top by the crown it might look like some king the 4th or some king the 3rd. On the back I just see a decorative cross







This next one looks like there is mother and child maybe, like mary and jesus perhaps on one side. The other side looks like a coat of arms, with a denomination of 2.








This last coin appears to have some silver. In the middle looks like a 4 legged animal, perhaps a wolf or bear. On the top I can make out the letters: REPUBLIC? Æ (AE) BERNENSA, or BERNENSI? It is worn at the beginning of republic so I am not so sure thats what it says- and at the end of the BERNEN word there could be more letters but its too worn. On the back I can make out the letters DOMI on top and aybe DEB on bottom. The middle appears like it was just decorative, but I can't tell.







Any help is much appreciated!!
