the first one not sure about that if its deserved a yellow card but the 2nd one damn that should have been a red card lol and the last one oh well he is a real madrid player what do you expect

no, he couldnt see the other guys leg on the second incident... Feghouli should not have been sent off...

he was just unlucky

I have to agree with knibis here. If you follow Feghouli's eyes, he's looking at the ball. And the first one was just a b*tch.

Bad day for him I guess

First one is a yellow card, it's a shit rule but if you block a free kick being taken deliberately or not it's unfortunately an automatic booking. 

However second one should never have been a yellow, as Dynastian said he is clearly going for the ball, he is not even looking at the player.

No he didn't watch, but we can't be sure at 100%.
