Would these plants enjoy the summer heat?

i was planning to put a : hibiscus, majesty palm, chinese fan palm, mexican fan palm, a banana tree and a pineapple plant outside this year, there isnt much rain and the plants would recieve shade for half the day and direct sun for the other half. The temperatures range from 20-high 30's during this sunny period that lasts about 6 hours. Is this a good idea?
