There are two versions of the Aramaic Scriptures - the Targumim and the Peshitta. There are probably many here more knowledgeable than I here, but I think that the Targumim were completed about a century before Christ, and the Peshitta about a century or so afterwards. The Targumim are written in a Hebrew script and includes only the Old Testament, whereas the Peshitta was written in Syriac script and includes both Old and New Testaments.
I don't think that there is consensus among scholars about which of the books of the Old Testament were originally written in Aramaic, but there seems to be some evidence that the Book of Daniel was written originally in Aramaic and not Hebrew (If I am wrong, I am sure I will be swiftly corrected).

Daniel Chapter 2 from the second part of verse 4 through the end of Chapter 7 is in written in the Aramaic language and with same script as the Hebrew scriptures. There are several less substantial occurences of Aramaic in the Hebrew scriptures detailed here: https://en.m.wikipedia.org/wiki/Biblical_Aramaic. All of the Hebrew scriptures are written with the same script.
