Is this flirting in the context of group settings?

We talk one on one mostly about nothing. He'll just lurk around me then finally ask me whatever comes to mind. It could be about a bathroom sign in our job hallway. Sometimes its about weekend tales or him reminding me of something we spoke about before and once about hypothetic couple stuff ( " a girlfriend would love that concert my friend went to. Just sit back with your date and enjoy").
If I'm in a group with my girls he'll wait until they leave to speak, even if he was speaking to me before they showed up. But if he's with his guys and I walk in room he'll start making jokes about the guys.
I like him but I never have guts to talk to him around other people until yesterday. We were all at a table for lunch. He was way opposite me. Everyone was talking about a show and I added my opinions. He was adding opinions as well and being more open than usual. And everytime I spoke he'd comment on my sentences specifically with my name ( Liz) each time.

-Fake example -
Random guy: it seemed crazy
Him: it was a little psychotic
2nd random guy: interesting though
Me: the 2nd part was creepy
Him: Liz , it was creepy?
Random guy: they dressed funny
Him: ha, what was that
Random Girl: I thought it was alright
Him: some looked ridiculous
Random guy: exactly but I actually liked a few things
Me: some parts of it were cool
Him: ( laughs) you don't have to be nice Liz.

Etc.

Are those his ways of flirting in the group setting? Making fun of his friends all of a sudden and making a round table of discussion personal to me by singling me out everytime he addressed my part in the conversation? Or is this just a friendly outgoing thing to do?
