I grow mangoes. Which cultivar do you have?

In any case it will most probably want to be repotted to something at least 3 gallons if you overwinter it in a greenhouse. They're fairly demanding of the soils. And you may want to figure out if you're allergic or reactive to turpentine fumes; a mango tree, regardless of species, in closed quarters is a highly aromatic beast, and some people have adverse reactions to them.....

I wish you the best of luck, and I wish I could get my hands on a lychee tree down here. They'd be ideal for the summertime heat, and I wouldn't have to spend so much on imported rambutans.

Also, if you're trying sapotilla, maybe look out for mamey sapote. It's a bit easier to grow in your zone, and the fruit is amazing!
