Dare Devils 3.  Once again, Ronald Byrd has done me a yeoman service, and rather than summarize him I'll simply quote him verbatim:

It's a shame that Dare Devils 3 appeared only in Kid Comics #3, because somebody seems to have put some level of thought into it.  Our story opens with the closing of a garment plant, and we follow three friends and fellow workers:  Clancy, Goldy, and Off-Key (a young Chinese man whose speech irregularities are, at first, limited to an occasional tendency to refer to himself third-person; Off-Key is the only one presented to have any sort of social life, as he has a girlfriend named Lucy Lee (needless to add, also Chinese)).  At loose ends now, the three decide to join the Army Air Force. Clancy and Goldy become pilots, but because Off-Key holds two degrees from engineering college (yet he was working in a garment plant; rather a depressingly accurate view of how things were for non-whites in the 1940s, huh?), he is sent to mechanic training.  The three reunite when Off-Key is appointed to Clancy and Goldy's plane (inexplicably, Off-Key has developed a cliched Chinese accent, not as bad as Blackhawk's Chop-Chop, but still noticeable; I guess the writer lost his train of thought), and they fly a bombing mission over Egypt (at one point, out of ammo, Off-Key substitutes liquid rotten eggs to incapacitate the enemy).  When the trio recover in an army hospital, Lucy Lee is present as a nurse, and she and Off-Key are to be married.  Brief and to the point, if a bit more mundane than the name "Dare Devils 3" implied.

Dart. Caius Martius was a gladiator in Ancient Rome. The gods gave him the power to flight so that he might fight for the rights of the average citizen. Unfortunately, one day he took on a sorcerer and is trapped in a block of stone. In the modern era he emerges from the stone to find himself a museum piece. He takes a new last name, "Wheeler," and begins fighting crime in modern society, which is just as corrupt as Rome. He is partnered with Ace Barlow, the Amazing Boy, who has the same costume and power. The Dart can fly and uses his gladiator's sword on the bad guys.

His arch-enemy is Wing Po, a stereotypical Chinese mandarin-type who hails him as "my illustrious rival" but who wants to get the sunken loot before Dean does. Dean is, of course, a very good diver and a good fighter.

But as a gesture of gratitude to Davey he swears not to hurt him, and he gives Davey a cloak that will protect him. Then the Demon goes out on a rampage and Davey tries to stop him. The "Prince of Good," a magician who imprisoned the Demon in the cave in "primordial times," ends up appearing and fighting against the Demon, and then the Demon is trapped underground. The Demon has vaguely defined magical powers, but is big and has superstrength.

Diamond Jack. To quote the indispensable Michael Norwitz,

Given a black diamond which was embedded in a ring, by an old magician from the Far East, Jack Lansing found himself able to use it to create constructs formed by his mind. If he wished to strike someone, Lansing just had to envision a boxing glove hitting his opponent. Need a handy jail cell, just think one up, and there would be one surrounding the crooks. He could also use his mystical gem to give him limited flight. Lansing was only limited by his imagination. If he lost his concentration, whatever magical object he had created would cease to exist, so will power was of the essence. He used the diamond to help him continue his adventurous lifestyle serving as soldier of fortune one year or treasure hunter the next.  He was never extremely adept at the use of the diamond.  Predating Green Lantern, he never donned a colorful, skin-tight costume.
