No complete rhymes: doctrinal /ˈdɒktrɪnəl/ is stressed on /ˈdɒk/, so a true rhyme would need the exact sequence /dɒktrɪnəl/. The listed words share the final spelling -inal and the unstressed ending /ɪnəl/ (or /ənəl/ for original), but their stressed syllables differ (e.g., /nɒ/, /krɪ/, /tɜː/, /kɑː/, /mɑː/, /əˈrɪdʒ/), so they are lookalikes, not rhymes. Note especially original, which is spelled -inal but pronounced /əˈrɪdʒənəl/.
