Two simple hands (PP 0.5/1) - did i played bad or smth?

[Akimka]

Two hands - one is flush/streen-draw, second is vs flush-draw. I didn't pretty sure should i be more agressive with my draw? Should i call raise?
And about second hand - had i any chances to wipe out flush draw before river? Should i raise on turn? Should i fold as soon diamonds falls?
