I managed to find these links
that talk about Scar's tattoo, part of which come back to fullmetal-alchemist.com forums…
Boiling down speculation from the above two links…
"Terra A Ndan Colia" could be "Land and reign sky" (literally, Terra=land A=and Ndan=reign Colia=sky)
However, it looks more like the surrounding "dop la" and "sic ca" are part of it.
"dop la" may mean "after the" ("dop" is questionable, but dopo is "after" in Italian)
"sic ca" may be "sic circa", sic=thus, circa=around (in English, usually meaning "around <date>")
"colia" may be "kolia" = "voice of god"
So putting them in the mix, you have:
"dopo la terra sic circa a ndan, kolia"
or "After the land in the time of Adam, the voice of God"
with "After the land in the time of Adam" probably meaning the afterlife.
Not much about the other phrase, but putting that together in the same pattern:
"cah bue aer hu ma v snon, glus"
cah=?battle bue=?arch aer=sky v=versus, rest is unknown unless "hu ma" is "human"
