#1 could be an unusual Vitro.
How many yellow patches on #2? If only one, then I'm stumped. If two yellow patches, then I'll put in another tentative Marble King. If one yellow patch and one patch of some other color then I understand a Vitro guess on it, but would still question it based on the shape of the yellow.
Sticking with Marble King on #4 and Vitro Conqueror on #3. Not gonna place any bets on the Marble King for #4, but it looks familiar to me. If I recall correctly, I got similar marbles in a Marble King horseshoe blister pack.
