I know the people on this forum seem like crazy gear heads, but you might wanna include an overshot of the engine so that they know where you're talking about, or at least the type of engine you have...

srry about that hope this helps

my guess is coolant temperature sensors

those vacuum lines probably should connect to something though

my best guess would be your water outlet pipe (reading the diagram in the Haynes Manual)

thats your water neck it goes into your water pump... The first sensor is a temp and the other I forgot what those are...

Does your car have EVAP? That looks like a mechanical Thermal Vacuum Valve (TVV) from my observations (the sensor wituout the electrical connector). It opens/closes the path of air or vaccuum at a preset water temperature

First two are thermistors. The first one (from left) is obviously the water outlet temp sensor for the ECU. I dont know what the second one is for. And I think Tony nailed the third.
