I'm not gonna lie, this is one big ball of a mess. Maybe you should start by cleaning it up a bit and better identifying your issue?

Probably one of the shittiest code written here, sorry. :-\
Surround your code with [code=cpp][/code] when posting C++ code on the forum. (But you already know that (http://en.sfml-dev.org/forums/index.php?topic=15303.msg108535#msg108535))
Use events only inside the event loop. (But you already know that (http://en.sfml-dev.org/forums/index.php?topic=15303.msg108535#msg108535))
Don't uselessly load the same texture twice, you can use the same texture on different sprites.
You apply velocity.y (which is what makes your sprites jump or fall) to sprite2, but sprite2 is only drawn when the D key is pressed, so unless you're pressing D while jumping you won't even see it jump.
