As for a lineup, you're Level 42... There really isn't much to help with that early in the game, because you don't have the combo potential with multi-chase characters or summons yet. Also, you're using an aggressive main character (fire), but a VERY defensive lineup with Gaara and Hinata. Have to pick one or the other when you're at low levels with a small ninja selection.

Going aggressive, just try to make a decent attack setup. Shy away from a character like Gaara who needs so long to use his ult, and really doesn't attack for much damage, and focus on higher damage with a guaranteed combo starter. Something like:

X - X - X
Kankuro - X - Main
Shizune - Kakashi - X
Skill: High float chase, or 10 combo chase if you don't have it.

Gives you good combo, massive poison damage, and overall high damage output, with a bit of debuff clear and heal from Shizune. Just be aware that Lightning mains using their mass-paralysis skill will be very strong against you, since you don't have a way to trigger Hinata's Repulse chase.

Grab Tobi from the shop as fast as possible and just go Kankuro, Hinata, Tobi main. Voila you now have one of the best and most standard f2p Fire teams in the current meta.
