1. Honda civic commercial, with the several different versions of the same guy getting in the car, driving down the road, and then all the different versions vote in little stands. Song is sorta electronic, I catch, "workin' on the streets" as one of the lines.
Found! It's "The Huddle Formation" by The Go! Team.
2. Geico commercial, with the caveman in the airport. He's on the walkway and notices the sign saying "so easy a caveman can do it" and he gets upset. It's a very mellow song, goes something like, "And everywhere I go...there's always something to remind me..."
Found! It's "Remind Me" by Röyksopp.
3. I think it's Verizon? Some cellphone commercial. I'm actually annoyed by the song now, but I just want to know who sings it! It's the "Whoa, whoa, whoa, whoa, somethin's got me started..."
