I'd go for a combination of stock footage real flame (preferably filmed specifically for this purpose, otherwise just composite together existing stock) mixed with some particle effects to spice it up.
On-set lighting will be vital to sell this effect. You'll also probably want to do some selective grading to enhance the lighting in post.
Second being water. Looks like water but in a beam
Possibly particle effects, but this'll be a tricky one. While you can shoot flame out in a beam, you can't really do that with water, so it's going to look a bit odd either way. You could try going for a pressure-hose effect, I suppose. In that case I'd probably try experimenting with physical effects on-set, or compositing actual liquid footage again. If you go down the compositing route, you might find that standard water doesn't show up against a greenscreen or black particularly well - maybe using milk or a coloured dye would instead, which could then be coloured during the comp? Just a guess, that one.
Third being earth. I don't know if earth can be done in Visionlab studio. I want... like... chunks of earth. If that cant be done, don't worry about it. I can get them elsewhere.
The particle engine should be able to handle bits of dirt, dust and debris flying around.
Lastly being air. I want it to look like... a gust of air.
Generally you can't actually see gusts of air, you can only see the effect it has on other things.
However, you could use a displacement map to give the air a kind of shimmer along the 'beam' - though that could end up looking more like some kind of heat ray.
For this one it'd be best to use a powerful fan on-set to blow things around for real, I can't really think of any other way of doing it. But then I'm not really sure what you want a 'gust of air' to look like.
Hope that's useful.
