Yes, you can use both. Split Jaw makes adapter clamps to join them together. As far as deep flanges are concerned, you shouldn't have any problems. Heck, LGB's equipment runs on code 215 from Llagas Creek with no problems.
Kevin is correct. Besides, he's been around G railroading for a while, so he's probably made more mistakes and corrected them than most of us.
Let's start by just answering the man's question. Yes, you can use code 250 and code 332 rail with joiners as stated.
On the issue of depth, I've been using nearly every manufacturer's wheels on my Llagas Creek code 250 aluminum rail. No problems with rail and flanges. Have bumped some ballast out of the way, but not a problem.
Use the smaller rail whenever possible if it looks good to you.
A lot of garden railroading is like Davey Crockett said, "Be sure you're right, and then go ahead." But remember that "right" is in the eye of the owner of the railroad.
One thing I forgot about is wheel flange. Some brands of cars and engines have flanges too large to smoothly operate on code 250 rail. I don't recall which brand it is, but a bit of research on this site will get you to that particular conversation. As best as I can remember, there are some wheel sets out there that have flanges so large that they will bump over the plastic "tie plates' molded onto the ties, causing a lot of derailments.

Connecting, yes they can connect.

Blending of track of different weights CAN be done. My personal recommendation would be to do it only where it makes visual sense to do so, like joining a "light weight" branch line or spur to a heavy weight mainline. An example would be when joining a trolley/street car line to your main service main line. In that case it make a visually appealing layout, especially if the light rail has significantly different tie spacing. Give a look at either Hilmann's Rail Clamps or Split Jaw Rail Clamps. I'm sure you will find what you need to do the job between the two brands, both are very reliable connectors (both reliable businesses and reliable physical and electrical connections.)
I was wondering if you could mix different codes of track together such as code 250 and code 332.
Any help will be appreciated.
