Second machine looks a lot like a lat pulldown machine. Is there a chair-type thing at the left of the photo that you can pull up and sit on? If so, then the round padded things come down and sit on top of your thighs to stop you being pulled into the air as you pull down on the hanging bar you can see right at the top.
This is actually a very useful thing if you want to add some pulling action into your program to balance out the overhead pressing, and/or if you like the idea of working towards a pull-up.
Lat pulldown machines are one of the very few machines that even the most ardent free-weight proponents will concede are pretty useful.
Third machine is a leg extension machine. This is probably very pointless if you're already doing lunges and squats; they're better for you and if you want to add weight, you can do them holding dumbbells.
I have no clue what the first machine is.
Wait, hang on -- does the overall triad-of-machines look like this?

In which case, the enigmatic first machine is a "multiple position chest / shoulder press".
