Can it charge a laptop?

Yes. The 65W USB-C output is enough for many thin-and-light laptops and tablets, though gaming laptops and workstations need more power.

How many times can it recharge a phone?

A typical phone battery is around 4,000–5,000mAh, so 40,000mAh is roughly six to eight full charges after conversion losses.

Expect several hours even with a 65W charger, since the battery is about four times the size of a normal power bank.

No. There is a single USB-C port, so devices charge one at a time.

Check with your airline. At 40,000mAh the pack is around 148Wh, above the common 100Wh carry-on limit, so it may need approval or be refused.

The power bank itself; a charging cable and wall adapter are typically sold separately, so confirm before you travel.
