Hello, and welcome to the forum!
I think your tiel is a female based on the colour of the cheeks (too pale I think for a male, but it could just be the photo).
About music, I think it is individual. My tiel likes Mozart, but hates Beethoven for example.
I don't know for sure as I don't have it, but I don't think AC is good for tiels.
It is not necessary to trim a tiel's wings. I haven't for quite a while as my tiel is very good at flying and definitely not clumsy. Some tiels bump into things while trying to fly because they are clumsy, so owners trim their wings. At any rate people usually don't agree on this, so you will have to decide for yourself what is better for your tiel.
Don't house your tiel with other birds, particularly other species. If you don't have the space for a bigger cage, are you able to keep your tiel out with you? My tiel is always out with me (although his cage is not small). He only goes in to sleep or when he is very mad and 20 minutes inside under the blanket usually calm him down.
