Is it Modern Irish you're looking for, or Old Irish, as was spoken at the time of St. Patrick? Either way, I can help you with the pronunciation.

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.

[ˈɸʲɛlʲɪmʲuːɾʲ ˈgə̯ɪːhə]

[ˈkoːhʌnˠoːlˠ ˈxɾə̯ɪmʲ ˈɣə̯ɪβʲ]

[ˈtʲeːdʲax]

[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.

Thanks! I'm not very familiar with IPA, but this is finally my excuse to learn!

Thanks! I'm actually not sure. Many of them are old names. Here are some examples:
