The regular definition of freezing something is when its turning it from liquid to solid, and since lead at room temperature alread is a solid it can't really be frozen. It can get colder though.
It doesn't mend the pipe. The pipe will still have a leak. However, you can use liquid nitrogen to freeze the water in a pipe and create a 'freeze block' which will prevent more liquid from getting to the leak. Once the freeze block is in place, it is much easier to repair the pipe leak.
It depends on how much water, how hot it is, and how much liquid nitrogen there is. The water will initially cause the liquid nitrogen to boil; if there's enough water and it's hot enough, it may make the nitrogen boil explosively. However, if there's enough nitrogen, it will eventually freeze the water.
Liquid nitrogen expands rapidly when heated, which can lead to a pressure build-up. If contained in a sealed container, this pressure can cause the container to rupture explosively. Liquid nitrogen itself does not explode when heated, but the rapid expansion can lead to potential safety hazards.
No, liquid nitrogen is extremely cold and can cause severe burns if it comes into contact with skin or mucous membranes. Consuming liquid nitrogen can lead to serious internal injuries, such as frostbite in the mouth, esophagus, and stomach. It is not safe or recommended to eat or drink liquid nitrogen.
If you drop liquid lead into cold water, the lead can freeze in a tiny fraction of a second. (This will vary depending on the quantity of lead involved.)

Mixing liquid uranium with liquid nitrogen would likely result in the rapid cooling of the uranium, causing it to solidify. The reaction would be exothermic and could potentially lead to the release of radioactive materials. It is important to handle uranium with caution and follow proper safety protocols to prevent any accidents or exposure to radiation.
yes and no. The liquid nitrogen is not toxic but in its liquid form it is at (around) -330oF which will freeze and destroy flesh on contact. If you (for example) freeze a banana with it you can smash the fruit with a hammer and it will shatter like glass - so its effect on your body is extremely dangerous. On the plus side it will very quickly return to a gaseous state - because it will get above the boiling point very quickly at normal room temperature (liquid nitrogen looks very much like boiling water if you have an open vessel). This could be dangerous in an unventilated room because you can't survive on nitrogen and you would, potentially, suffocate as it reduces the available oxygen in each breath. As the leak will be obvious and, presumably, it is in an area where dealing with liquid nitrogen is a common occurrence so it will be ventilated and safety equipment is available the risk is small, however a leak of any vessel under pressure could lead to catastrophic failure especially because such temperatures can make metal brittle and the resulting explosive decompression could cause a lot of damage.

Yes, liquid nitrogen can cause a rash or skin irritation due to its extremely low temperature, which can lead to frostbite or cryogenic burns upon contact with skin. This can result in redness, blistering, and peeling of the skin. Proper protective equipment should be worn when handling liquid nitrogen to prevent such injuries. If skin contact occurs, it is important to seek medical attention.
