Stuck on Snowfield 7, Mountain 2, Frozen Lake, & Ice Castle

[shine]

So I've been stuck on the stages as listed in the topic name for a couple of days now. I'm getting kind of frustrated and I need to help with what to do. I've read guides, try many weapons & compos, but to no avail.

Here's my current team & stuff. Advice would be appreciated. c:

Mountain 2 is super-difficult. I try to save that one for last, regardless of other levels.
