I'm trying to stick on anti-pigeon spikes on top of my window air conditioner and want a non-permanent solution that I can take off when I put it into storage.
Is there something I can use that's weather-proof but also removable at the end of the season?
Since it sounds like it might be difficult for you to get to a lumberyard to build your own solution, you might be better off using a pre-made product. AC-Safe, makes Universal Air Conditioner Supports that might be useful in your situation.
The system requires you to screw the platform into the window sill (which may or may not be possible in your situation), then simply rests against the outside of the building to support the A\C unit.
I've also seen brackets that mount to the bottom of A\C unit itself, and offer support against the outside of the building (but I was unable to find an example online. I think Thermwell makes them).
In order of questions asked:
It is best to install the indoor unit near the area of maximum heat loss and gain. Above a window is a fine place, provided you have space to run the refrigerant piping and condensate line.
Near a corner is okay, but a less central location means there will be a longer time required to circulate air around the room.
As a licensed refrigeration person I can say that outdoor installations near the ground are usually more pleasant to service than those that are on a roof. Most modern mini splits are very quiet. As long as the outdoor unit is not directly next to a window, you probably will not be bothered by the noise.
Outdoor unit installed above or below the indoor unit does not matter as long as the total lift and length of piping is within the manufacturer specifications.

If you don't object to a product with an analogue in hook and loop tape, but more durable and substantially stronger, consider to locate 3M Dual Lock tape. It's available in various widths and lengths as well as different adhesive types. The strongest stuff has a gel type of adhesive, not quite foam, but squishy in a fashion.
The pieces are not "gendered" as with hook and loop. The tape has tiny stalks with mushroom heads that engage the other mushroom heads (get your mind out of the 60s here!) to form a very strong bond. The adhesive is weather resistant but I'm not so sure about sun resistance.
You'd attach one piece to the spike and one piece to the cleaned surface of the air conditioner.
The magnet idea is a good one, as you'd need only one magnet if your air conditioner has a steel casing.
