Hello. First of all i wanna say that, my english is not my native language so i may make many mistakes.

Ok, i have no idea how should i check if key was hold for some time, i mean i press space and i wanna to know if it was hold for some time or released, how am i supposed do that?

Every frame check if the key is pressed, if it is add the delta time to a variable to track how long it has been pressed, if it is not pressed then set the tracked time to zero.

Could you really not have tried to figure it out on your own before asking?
