Well, it's Modern Irish, with some transcription errors: "felemuir" should be "feilmiúir" a dialect form of "feirmeoir"; "comthineol" should be "comhthineol", a dialectal form of "comhthionól" (looking at the link you sent, I see that the lenition is missing from the "m" in "domnach" too, which should be "domhnach" [ˈd̪õːnax]).
Here are the pronunciations for those. I hope you're well versed in IPA.
[ˈkoːhʌnˠoːlˠ ˈxɾə̯ɪmʲ ˈɣə̯ɪβʲ]
[ˈpɔl̴̪ ə ˈtʲeːtʲə]
[ˈɸʲɛʃ tʲiː ˈxɔnaːnʲ]
If really necessary, you can replace [ɸʲ] with [fʲ] and [βʲ] with [vʲ].
Don't hesitate to ask if you need any further explanations, I know it's complicated.
