A star of five solar masses would reach the main sequence quicker or slower than the sun?
A star reaches "main sequence" when it starts converting hydrogen into helium. This occurs, when the temperature of the core reaches about 10 million kelvin. When this happens depends a lot on the rate of accretion of matter onto the star.
Larger stars would have to amass large quantities of hydrogen quicker than smaller mass stars to gain their size before becoming main sequence stars.
Difficult to answer, but a "best guess" would put the high mass star first.

Size of main sequence star?
A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
How long does it take an M-type star to reach the main sequence compared to a star like your sun?
The main-sequence of stellar evolution is followed by stellar ignition of a protostar (Assuming it's not a failed ignition). Stars are not classified in the Hertzprung-Russel diagram's main sequence until stellar ignition has been initiated. Additionally, the length of time it may take for a protostar to reach T Tauri and initiate stellar ignition depends on the mass of the protostar. The heavier, the quicker. The lighter, the slower. For an example, it takes about 1,000 years for a 1 solar mass protostar to initiate stellar ignition. So since stars cannot be classified in the main-sequence before they initiate stellar ignition, you can't know the difference in time. since you won't know what will be what class star. The main reason is because the mass of the protostar fluctuates as it accretes matter, becomes T Tauri type and begins stellar ignition. At stellar ignition, a T Tauri star can lose up to 50% of its original mass.
How long does it take for a average tree to reach its full potential?
The time it takes for an average tree to reach its full potential can vary depending on the species. Generally, it can take anywhere from 20 to 100 years for a tree to reach maturity and achieve its full size and reproductive capacity. Some slower-growing trees, like oak or redwood trees, can take centuries to reach their full potential.
What is the suns next stage after 5 billion years?
Theoretically, in 5 billion years, the Sun will still be in the main sequence. 5.4 billion years (estimated) marks the end of main sequence, where it will be in the intermediary point between a main-sequence star and a post-main-sequence red giant, where it will slowly reach over 200 times it's current mass over the course of about a billion more years, at which point it would be classified as an official red giant and be fully burning helium-4 as a main source of fuel as well as burning a hydrogen shell it built up during the main-sequence. After that point it will eject most of its mass into a planetary nebula and slowly cool as a stellar remnant over the course of a few quadrillion years until it reaches 3K.
What is the weight of star?
Stars do not have weight they have mass. Our Sun is said to be one solar mass or 1.98892×1030 kg. There are stars smaller than our Sun (read dwarfs) which can be down to 0.075 solar masses and stars much much bigger than the Sun (Hypergiants) which can reach 80-150 solar masses.

Why are there no stars with masses much greater than 100M?
Stars with masses greater than 100 times that of the Sun would burn their fuel so rapidly that they would not have enough time to reach the main sequence before exhausting it and ending their lives in violent supernova explosions. Therefore, there are no stars with masses much greater than 100 solar masses currently observable in the universe.
How long does it take an M class star to reach the main sequence compared to a solar type star?
M-class stars take significantly longer to reach the main sequence compared to solar-type stars. While solar-type stars (like our Sun) typically take about 10 million years to reach the main sequence, M-class stars can take anywhere from tens of millions to over a hundred million years, depending on their mass. This extended duration is due to their lower mass and slower rates of nuclear fusion, resulting in a prolonged period of contraction before they achieve stable hydrogen burning.
Why might the plague have been slower to reach eastern Europe than it was to reach western and northern Europe?
All of thetransmission of the plague was by fleas carried by rats or on clothing or cloth. Trade may have been slower to eastern Europe.
How do different masses fall in a vacuum?
In vacuum, all masses big and small fall with the same acceleration, and reach the same speed in the same amount of time.
Does one mass reach the midpoint before the other explain your answer?
In a scenario where two masses are released from the same height but have different weights, they will reach the midpoint simultaneously if we neglect air resistance. According to Galileo's principle of falling bodies, the acceleration due to gravity is the same for all masses, meaning they fall at the same rate. Therefore, both masses will reach the midpoint at the same time regardless of their weights.

What is the life span of protostar?
A protostar takes about 100,000 years to reach the main sequence.
If two masses conected with string and hanging from a spring attached to the roof are pulled down and released can the tension reach the value cero?
The string can be extended up to its extended length, but can not be compressed. When the two masses reach its maximum velocity, the spring started its compression phase and the string begin to bend. At this moment the tension on the string becomes zero. When the two masses reach its lowest position, the acceleration becomes maximum and is pointing upwards. Ignacio E. Olivares
