If an outgoing girl touches you does it mean anything?

So I've actually become pretty comfortable friends with my crush (except I've never asked to hangout) and she is an outgoing person to people she knows. She highfives people alot and play punches even her guy friends and I feel threatened and jealous. Except she has grown a bit friendly comfy with me.

When we sat next to each other in class I would try leaning closer to her with my elbows and stuff lol. She didn't seem to mined as she leaned in the same direction. Then she would joke about how I need to stay on my desk while I teased her by placing my entire arm on her desk.

She also seems fine with touching my hand as she has grabbed it and actually held it to draw an inside joke on it a couple times. (twas awkward with my guy friends watching) and she would always poke me. When I tried to poke her back she would do a cute little karate shop while I kept teasing her. After a while she stopped doing it and I actually grabbed her wrist, pat her hair and even her thumb to unlock her iphone lol. (I've friendzoned myself huh).

We've kinda tangled our arms around in class before when I have something she wants which I usually end up stopping because people start noticing and it looks weird…

The big puzzle is when I text her she will take hours to respond even a whole day. Then she will respond quickly after I replied back again for a while then completely drop off. Its frustrating cause I see her liking instagram pics. I'm confused and its too awkward randomly ask to hang

Sorry… But this just means that she's comfy with you. Maybe a close friend or something, but that is it.

Take it from me and I'm a girl. Based on your description she doesn't like you as you like her.
