Tigrounette - Tig-ru-net
Meribellule - Meribelul
Galaktine - Galaktin
Zou - Zuu
Azrou - Ažruu
Pikashu -Pikashjuu
Narayan - Nara-ya:
Larirette - Lari-rett

The u in 'Meribelul' sounds a bit like ü. ([yː])
The a in 'Galaktin' sounds maybe a bit like ä. ([æː])
Guess I like simplifying the names in a way. :)

tigrounette = tig - roo - nay
melibellule = mel - E - bell - you -ill
pikashu = peek - uh - shoo
zou = zoo
galaktine = gal - ack - teen

Pikashu-Pik-a-shoo

Zou-zoo

Galaktine-Galk-tine

Tigrounette - /ʧi:groʊ'næʧ/
Melibellule - /meli:be'lu:li:/
Zou - /'zoʊ/
Galaktine - /gɑ:lɑ:ki:'ʧi:ni:/
Pikashu - /pi:kɑ:'ʃu:/

The /r/ sound is pronounced as in "little", and not as in "rose"

If Galaktine is french, she probably pronounces it
Guh-luck-tea-neh

"The nay-mehs of add-mins."
