The middle one should be:
Argent, on a chevron sable between three martlets* sable, three crosses crosslet** or.
The rightmost one should be:
Sable, a wolf or, three mullets argent in chief.
* I guess. Every book on heraldry I have read says that "martlets" are traditionally depicted without legs, but has not given any alternate term for songbirds with legs. I can only assume these birds are meant to be martlets, perhaps painted by someone unaware of the convention.
** These might instead be crosses botonny. A cross crosslet has a crossbar on the end of each arm, and a cross botonny has each arm terminate in a trefoil shape. From even a slight distance it can be hard to tell the difference between the two.
