The first antenna looks like a homebrew addition of wire mesh to an off the shelf corner reflector. I would be amazed if that second reflector actually helps at all, never seen that on an antenna before.
The second and third antennas look like standard issue Radio Shack VHF-only antennas. Probably OEM'd by AntennaCraft, but it could be anybody. They'd be terrific for FM, but in most parts of the country the low-VHF elements would be useless.
