Your first insect is some kind of Pentatomid (stink bug), looks predaceous. The second is some sort of weevil (Curculionidae), and the last is a mole cricket (Gryllotalpidae). The weevil looks very similar to something called the "giant palmetto weevil" in Florida, they may be in the same subfamily or something. As for the stink bug, it's "smile" is cute! I can't give species or genus, but now you've got an idea.
