How hot should a green house 'not' get when it has pine bonsai trees, veggies %26amp; roses in it? What temp inside a greenhouse would be considered too high for these plants or in general?

Consult greenhouse books in the library for specifics, but, in general, 80 degrees is about max for most plants, including cacti. Above that temperature, humidity is likely to be zilch, and infestations of aphids and mealy bugs, among other nasty things, are quite likely.
Add a fan, to help evenly distribute heat, and a large, shallow pan of water, to help keep humidity at an acceptable level.
