The first one is an ancient metal termagant. Termagants are the lowly footsoldiers (hoofsoldiers, technically) of the Tyranid hive mind, and have gone through several iterations over the years. Personally, I think that the old metal models capture them best: small, fast, vicious and nasty, scuttling down pipes and through the underhive, looking for things to shoot and jab.
In keeping with this image, I based the termagant on a cast-off piece of plastic and painted the base to look like a metal walkway rusted by the toxic sludge below it. The termagant itself was not converted, and was painted an unhealthy fleshy colour, like a mixture of the facehugger from Alien and the last chicken in the rotisserie section of a large supermarket, spinning sadly on a long-neglected spike, avoided by all but the very drunkest customers.

The next model was a Squat "living ancestor". Apparently, this guy used to sit in a sidecar, and was propelled into battle by his biker-dwarf brethren. I have no memory of buying him and I certainly don't have his bike and sidecar. I gave him a pair of Ramshackle Games robot legs and the engine/exhausts from a tractor.
Since I couldn't cut him off his resin base (as I quickly discovered), I broke the edges of the base off to make it look like rock. He then got a red paint job.
I like this guy: I could see him as some sort of guildmaster or other important, but physically feeble, type. Perhaps he represents a merchant guild. I could see him having a Dickensian name like Jedediah Clench. He's probably really good on the local football team, assuming that he doesn't die of old age mid-game.
