That plant is a Schefflera (probably Schefflera actinophylla) and if it is pesticide free, you can of course use it in a tokay enclosure.
Not a plant for tokays to climb on, but contributes to giving shelter and improving the cage climate.
Schefflera do thrive well under relatively low light cobnditions, which mak them quite suitable for nocturnal geckos tanks.
