Welcome!
Yes, one gate is needed for each aircraft that will be on-ground simultaneously. Using strategy with aircraft route scheduling/placement you can position aircraft so that you need less gates, like you mention instead of basing all your aircraft out of 1 airport, you could split them between various airports. Additionally you can lease shared gates, those will charge you a per-use fee instead of a weekly lease.
Connecting passengers are not yet implemented, but planned for some stage in the future.
Fleet commonality is worked into the per-flight maintenance costs, if you have multiple aircraft in the same family you will receive a discount on MX costs. The more aircraft you own, the greater the discount, up to a certain point (around 80 aircraft). Maximum discount is around 30%. It is a logistical growth formula so discount starts off slow, then grows, and then levels off.
