Very slightly, as more pressure means you have pumped more air in it. Excluding weight of air, the weight of ball will not change with the increase in pressure inside the ball

No. Weight = mass x gravitational attraction and both of them are unchanged. Only density changes (increases).
The above answer was based on applying compressional pressure from outside on a solid ball (or even a hollow ball). But the second answer of increasing air pressure is also OK. In that case, the weight goes up albeit slightly.

Yes. Air is matter, so it has weight. If you add liquid to a beaker, its weight increases. If you push more air into a ball, you are forcing more matter into a container, so its weight will increase.
Weigh an empty car tire or inner tube. Then pressurize it and weigh it again. It will be heavier.

Yes, you do increse it's weight. Think of it as putting more socks in a backpack. The more you cram in there the heavier it gets.
