Need help balancing sun & water in outdoor orchid orchard

[Dejinah]

Please help the clueless...

Question #1. I'm in zone 9B (West Central Florida). I have thirty or so orchids living in a cluster of trees outside (only option). No one gets full scorching mid-day sun but everyone gets some level of direct dappled light. Some get it during prime time but most get it when the sun is low in the sky early or late in the day. If it's windy, everything is fubar.v shot below was 7:30 am.

My current victims are mostly phals, vanda's, dendrobiums, oncidiums, a few cats, plus a paph, a miltassa, a zigonesia, 1 brassidium, 1 maxillaria tenluifolia, a zingo, a cynoches, a vanilla planifora & a few mysteries. As a true beginner, don't know what they need. I have no idea who needs what kind of light, or how to manage them in this location. Or better said, no idea about anything. Can you help?

Question #2: We get monsoon-level rains periodically. They go on for weeks. I just repotted all of them into slotted, mesh hydro or slat baskets. I used a bark mix & threw as many semi-hydro sees in as I could afford to buy. But I'm still freaking because currently they're getting flooded almost daily, sometimes several times a day. Again, keeping them outdoors in an environment that I can't control is my only option. Please advise how can I deal with these conundrums? Thanks bazillions!
