From a practical standpoint when you are old enough to follow instructions, and have the strength and coordination to fire a gun. Legally- age will vary from place to place- but in most cases, when under the supervision of a parent or an instructor, at any age. My children (and grandchildren) began shooting with me under direct supervision at around age 10. Some people may be ready younger, some older- some never.
yes you can you fire .22 rounds out of a No.8 rifle.
To be able to manufacture firearms (modifications which allow something which is not intended to fire live rounds into something which does fire live rounds is considered manufacturing) requires a Type 7 or Type 10 Federal Firearms Licence. On top of that, you wouldn't be able to - even if you did manage to get a live round to fire through a cap gun, the most likely end result would be that it would end up exploding, which would come with the risk of injury or death to the firer. Such replicas have to be completely incapable of firing live rounds, or else they would be classed as firearms by the BATFE - the BATFE even confiscated 30 airsoft guns imported from Taiwan, claiming that they could somehow be converted to fire live rounds.
No such thing as a blank gun. You can put blanks in a gun though.
16 thousand rounds.

No.
The M16 assault rifle has a cyclic rate of fire of 700-950 rounds per minute, and 45-60 rounds per minute in semi-automatic fire.
No.
Cyclic rate is 800 - 1000 rounds per minute. Rapid fire rate is 200 rounds per minute. Sustained rate of fire is 100 rounds per minute.
The fire rate of miniguns starts from around 2000 rounds per minute and minigun that has the fastest rate today shoots close to one million rounds per minute.
The original AK-47 had a cyclic rate of fire of 700 rounds per minute. The "modernized" AKM (manufactured from 1959 onwards) had a cyclic rate of fire of 600 rounds per minute. Cyclic rate of fire meaning that, if you had a magazine with such a capacity loaded, and you just held down the trigger, and you could fire off as many rounds without the weapon overheating and becoming defective.
12-20 rounds depending on caliber and magazine.
