Confusing situation?! Three guys?

[Crystal Unclear]

So there's this guy in my school, well THREE of them, that I have a weird feeling might be interested in me. Let's call them Mason and Mike and Greg. They are all friends.

I was new at my current school in September 2013 and a few weeks in, Mason and Mike added me on Facebook. I find them three cute which is confusing! But the one I find the cutest is Mike. When I posted a new profile picture in September, Mike liked the picture. I posted a new one this month and this time Mike and Mason liked it. I only became friends with Greg in December and what is weird is that he randomly decides to add me and he is practically best friends with Mike and Mason?

When I drew a picture once, my classmate saw it and wanted to take a picture of my drawing it to put it on Facebook. When he did, he tagged me in the photo and Mike commented 'it's beautiful' and what was strange is that he is not friends (in school) with my classmate. I notice that they all kinda look at me, and I've caught Mike and Mason especially glance at me a few times while I was with a friend/with friends. Even today, I came into the football field to sit with the rest of my class and Mason and Mike were both there. I said my friends name and asked him a question and both of them literally sat there and stared at me. As I walked past to sit on the other end, they follow me with their eyes and Mason sarcastically answers my question (he was trying to be funny) . Mason has made conversation with me randomly a few times but I have never properly spoken with Mike or Greg. Yesterday, I also went to the football field and sat there with my friend. A few minutes later, Mike, Greg and a friend of mine sit a few meters away from me. My friend calls me and both Mike and Greg turn and look straight at me throughout the whole time my friend was talking to me. Even in the lunch line I was on my phone, i look up and I see Mike staring at me and he turns around as soon as I look.

What does this mean?! Do you think they like me?! My friend jokingly once said that maybe Mason and Greg look at me and added me on Facebook because of Mike and that they have talked about me before. I admit that I think Mike looks like he is more interested than the other two.. do guys do this if their guy friend has a crush on a girl?
