Andraste basbhcoradhan - "Andrasta brings death to the wicked"
Inscription on a British idol to the goddess Andrasta
Andraste is mentioned only by Dio Cassius (or Cassius Dio) as invoked by Boudicca before battle. There are no dedications to her. Bás means "death" and coradh means a bend in a road, both in Irish. What he puts into Boudicca's mouth in Book 62 of his Roman History is largely ridiculous, repeating all the Roman ideas of the Britons as savage cavemen, but this one is good even though she probably never said it:
"Let us show them that they are hares and foxes trying to rule over dogs and wolves." (LXII, 5)

Tyn fian dwma fiatua!
I am a freeman in a free state!
Last words of Dumnorix. Refused to be a hostage, and killed by Julius Caesar's men
According to De Bello Gallica Book 5, VII: "He, [Dumnorix] however, when recalled, began to resist and defend himself with his hand, and implore the support of his people, often exclaiming that 'he was free and the subject of a free state.' They surround and kill the man as they had been commanded; but the Aeduan horsemen all return to Caesar." We don't have the original Gaulish and if we did, this certainly wouldn't be it. *Rêdis biu, tôtios tôtas rêdis imi or something like that.

Timidios di Albhae Bren!
For the true king of Britain!
Rallying cry of the Catuvellaunians/Casse
This is mocked-up Celtic again, a mixture of modern Welsh and Irish. You'd want something like *Rigonui uerui Pretannion... but how would we know what they shouted anyway? It's not in Caesar.

Toutava, marae, da augu, tosgo, mavi Vergalla!
For tribe, family, and honor, forward, sons of Great Gaul!
Inscription on a statue of Dis, the mythic founder of Gaul
Dis isn't the mythical founder of Gaul. He's a Roman god, equivalent to someone (we're not sure who) the Gauls believed in as some sort of ancestral God - if Caesar is correct.

These quotations look very suspect, and I'd ask for sources for them:

They say I am most beautiful of our tribe. How exquisite that I am then held to high standards. It is an honor to reward the gifts of the gods with dutiful service.
Orriagh Raighnaigha

I care nothing for my own life. In the service of the tribe, the king, and the kingdom, are all that matter. I must defend it, and all who live within it.
Llwnn yn Orddae

Rabo!
Ancient Celtic or Iberian warcry; forerunner of the dark age and medieval Gaelic 'Abu'

What Celtic writings do we have from (roughly) the EB period that are genuine? Unfortunately, there isn't much in Gaulish that's at all warlike... geneta imi daga uimpi is a well known one that means "I am a good and pretty girl". One of the longest Gaulish texts is the Larzac tablet, a long complaint and curse on a woman who swindled the author over some livestock. It includes the words: sue cluiou se dagisamo cele uiro íono ue ííobiíe beíiassu sete which, paraphrasing Bernard Mees' translation is "A hearing for this best companion, true and just, is desired: may you begin punishing!" As for the Britons, we seem to have nothing but coin legends and nothing but Ogam stones saying "X son of Y from tribe Z" for the Irish. There's no Gaulish in Egypt either: the temple grafitto in question was written by Galatians, but in Greek.

Here's some warlike Old Irish (search for "excellence of the ancient word" for more stuff like this)
dom roich mo coilg ndaighneimhneach,
frithálta mo sciath
"To my reach, my sword of burning poison, having attended to my shield"
-The Druid Mogh Ruith, Forbuis Druim Damhghaire
