Are these signs of attraction of a man to a woman?

Anonymous
Several things that happened with guys...are all of these signs that he was attracted to me?

1) Guy sitting next to you with a diff girl he is friends with on his other side, but he puts his arm around your chair the entire meal, and chooses to sit next to you, look into your eyes, smile, sit with his body towards and much closer to yours than hers.

2) This guy called me over and said "come here I want to tell you something" and so I did and he rested his arm on my shoulder and stood really close to me..practically whispering in my ear

3) If a guy walks up to you and stands really close facing you and puts his hands over yours

4) If a guy raises his eyebrows when he sees you

5) If you are working with him on a project or whatever and he gives you a lot of random smiles with eye contact, and he is the type who doesn't smile that much/is very sarcastic

These happened with a few different guys recently. I'm pretty sure they are signs of attraction..am I correct?
