Multiple replication forks working in concert, can be replicated in about 8 hours
Prokaryotic DNA replication has a single origin of replication, leading to two replication forks. In contrast, eukaryotic DNA replication has multiple origins of replication, resulting in multiple replication forks forming along the DNA molecule.
Prokaryotic DNA replication typically proceeds bidirectionally from a single origin of replication, resulting in two replication forks. Eukaryotic DNA replication is more complex due to multiple origins of replication, leading to many replication forks scattered throughout the DNA. The exact number of replication forks in eukaryotic cells can vary depending on the species and cell type.
Helicase unwinds the double-stranded DNA by breaking the hydrogen bonds between complementary base pairs. This creates two single strands of DNA that can be used as templates for DNA replication or transcription.
The DNA polymerase enzymes can only operate from the 3' end of the chain to the 5' end, not the other way. The two helices that make up the double helix of DNA are oriented oppositely, as shown in the diagram above, making the DNA polymerase enzymes move in opposite directions.
Replication forks tend to unwind the DNA helix, separate the double strands, and synthesize new strands of DNA in opposite directions. They are formed during DNA replication and move along the DNA template strands as replication progresses.

because it just is
No, the whole point in forming multiple replication forks is to reduce the time it takes to replicated DNA by replicating several sections of DNA at the same time, so that each polymerase enzyme has to copy less of the DNA. As a result replication finishes earlier than it would if one polymerase were to replicate the entire strand (as it would operate at the same speed - about 1000 base pairs per second). The human genome has about 20,000 origins for replication, which will produce 20,000 replication forks. It is necessary to have this many because the human genome is so large (3.3 billion base pairs). Without 20,000 origins, DNA replication would take close to 20,000 times longer.

DNA replication begins in areas of DNA molecules are called origins of replication.
In prokaryotes, DNA replication occurs in the cytoplasm. The replication process begins at the origin of replication on the DNA molecule and proceeds bidirectionally. Multiple replication fork structures are formed to speed up the replication process.
Two replication forks are produced when DNA denatures at an origin, allowing for bidirectional DNA synthesis. Each fork moves in opposite directions along the DNA strand, with one moving towards the replication fork and the other moving away from it.
Not sure, but good question! You may have to ask a doctor.
Strand displacement replication is not a likely method of DNA replication because it involves the formation of multiple replication forks which is not supported by the structure of DNA, which consists of two antiparallel strands.
