OOC: Woah.
1st check: Rocco, aid with perception, failed
2nd check: Dante with Stealth, success
3rd check: Nementah with Nature, success
At this point, 2 success, 0 failures.
Then Rocco rolls again an aid but specify (as he should) that it's for round 2, aid another, bluff, successful
At this point there is no aid another bonus in the bank for the two remaining check for the round from Ibram and Renquist since the only successful aid was done early.
4th check: Ibram, rolls a 3 with a +18. Bluff. Normally he rolls +11, I have to wonder where the extra +7 comes from?! I am thinking that you are thinking : Word of Friendship + Aid another. If that's the case, Words of friendship works only on diplomacy and as I pointed out above, Rocco's aid was for next round. Which would mean you rolled a 14 and failed. Unless you can point out to me a bonus I might have missed.
5th Check: Renquist with intimidate. I did say 2 bluffs. Intimidate certainly could have been one of the 2 non bluff success required ('Good cop, Bad Cop' routine) and is what I meant by 'improvise'. I rather like it in fact. But the two 'slots' had been filled by Dante's stealth check and Nementah's Nature check. Also good calls, imo. At this point, the guards think you are credible as mercenaries. They still need to be convinced you mean no harm so they need to be bluffed.
So I'll rerout that intimidate as an Aid for bluff. It's acceptable as such (again, the cops routine).
Tally; 2 successes, 1 failures (Or 3 successes 0 failures if it turns our I forgot a bonus for Ibram).
Round 2:
Rocco acted, everyone else is up, +4 aid bonus in the bank.
