This category of monster consists of those whose forms are basically human, but with additions or mutations. There does not seem to be a default posture common to all of them. When blazoned “proper”, the human parts are Caucasian (pink) unless otherwise specified.
The “angel” is a human with a pair of wings on his back; it’s a period charge, found in the canting arms of von Engelhoffer c.1450 [Ingeram 140; also Siebmacher 97]. Its default posture is statant affronty, wings displayed (frequently displayed inverted) [Parker 10]. A specific variant of this is the Archangel Michael, so named in blazon: winged and haloed, but armed and armor-clad (and frequently depicted vanquishing a dragon underfoot).
A Society variant of the angel is the “standing seraph”, with six wings: two with tips up, two with tips down, and two covering the body. Like the angel, it’s statant affronty by default. (These are not to be confused with the “cherub” and the “seraph”, which are winged heads; these may be found under (human) head.)
The “fury” is a creature from Greek myth, a winged woman with serpents for hair. It appears to be unique to Society heraldry.
The “satyr” or “pan” is also from Greek myth; it combines the torso of a human with the hindquarters of a goat. It is horned, and may be shown playing a panpipe. The satyr is found as an heraldic charge in the arms of Arcos, c.1540 [Nobreza xl]; though cantingly armed with a bow, and blazoned as a “sagittary”, the creature has two feet, not four, and they are cloven.
The “troll” is a charge from Scandinavian heraldry, found in the canting arms of Trolle, c.1440 [Raneke 412-413]. (It is sometimes, erroneously, blazoned a “devil” outside Scandinavia.) The heraldic troll is distinguished by having no head: its face is embedded in its torso. It has clawed hands and feet, and a tail; by default, it is shown passant, with the head in full view, and one hand holding the tail.
Finally, there is the “demon” or “gargoyle”, like the satyr in having a beast’s hindquarters, but with the addition of bat-wings, a barbed tail, and sometimes talons. Unfortunately, its best-known heraldic use, in the arms of the City of Brussels, dates only to the early 19th Century. Demons depicted in period books of hours vary too widely in appearance to be reproducible; therefore, pending evidence of their use in period armory, demons are no longer permitted in Society armory.
