My strategy is to first, not use my main (save her for later fights, 10-12), and start with a team of 3 star Sasuke, Sakura, 3 star Naruto, and Tenten (I realize, you don't have 3 star Sasuke or Naruto yet, but this team only works with them being 3 star). They should be able to get through at least the first 6-9(maybe) fights and not die, if you utilize them correctly.
Of course, you c*ways use the classic Team 7 (Kakashi, Sakura, Naruto, Sasuke)

(If Sasuke dies, you can replace him with Hinata, although you won't get as much combos/dmg done.)
The second team, I use, when all/some fall (by now, you should be at least at 6-9th level, 9th preferably.) You can now use your main, Hinata, Kakashi, and Kabuto(since you mentioned you were going to get him. He's pretty useful.)
With skill set of:

These 2 teams get me through, but of course, I'll provide a couple more in case your some ninjas from your second team die.
For this team, in case Kabuto dies, cause the AI DOES aim for Kabuto frequently.

(Not alot of combos, I'm afraid, but it does decent damage, and has immobile, paralysis, and ignite. So nice, amirite?)
Skillset being:

Basically any combo will cause immobile to your opponent, isn't that nice? Kakashi will cause paralysis with Lightning Blade, and Ignite with Fire Ball Jutsu. Unfortunately, I can't find a way to utilize Hinata's Sealing Point Palm Strike (cause acupuncture), so until you get to lvl 55 and get a summon, Hinata's acupuncture will have to wait. :C
Another one, if Kakashi dies, cause holy heck, he is pretty squishy. (As well as Kabuto)

(At this point, combos is not always power, but status effects are. Got Immobile, Poison, and more poison. Plus heals from Main and Karin)
Skillset of:

Also, if you upgrade Temari and Kankuro to 3 stars, you c*so use them too. Obviously the Sand Siblings would work well together.

(Gaara is a good shield, plus Kankuro's puppet.)
Skillset: (For poison, immobile, and healing)

Another skillset:

Well, if you do count them all up, you'd realize the total is 13 ninjas, but these are all suggestions, especially the Sand Sibling team. Hopefully this helps you in Survival Trial! Plus, you can retreat as much as you want if something goes wrong, don't be afraid to abuse that opportunity! C:
