Yes, they are quite easy to get. 

1st is with goblins, just walk into them where you first met the orc camp

2nd is you being caught in the net trap

3rd is the girl stuck in the window of the tavern, just click on her few times and go to the tavern bathroom, then there should be an orc outside next to her

4th is the mushroom that puts you to sleep in stone doors/gates with spiky vines on them. right before you meet the wolf I think
