i want to know would higher horsepower means higher pressure for an air
compressor, also would this compressor reach 75 bar if the air compressor is run by 10 horsepower engine.

Pressure attained is a function of numerous parameters: engine power being just one.
Also relevant are compression ratio, seal efficiency, flow rate.
In theory I could attain arbitrarily high pressure using a hand pump with good seals and mechanical advantage. Horsepower and pressure do not
correlate directly.

That looks like a car ac compressor. First you would need to address the oiling issue, you could open it and fill it with high temp grease or use an
oiler in the intake and an oil separator at the output to collect the oil mist.
You can look for more info on the internet as these are used for onboard air in off road vehicles.
In no way you will get 75 bar from it, you will blow the seals and probably the head off; I wounldn't be comfortable with anything higher than 200psi
(~14 bar) . That kind of pressure is really dangerous.
You need a high pressure compressor, I don't think you can get those pressures with any meaningful flow with a one stage simple compressor like this
one

that compressor MOP will be 500 PSI or it would be disallowed by safety standards, this is with all refrigeration gear for standard old gasses, 410a
series MOP is 600 or better.
it design head will be 300 psi in automotive applications (Cars condensers suck for efficiency!)
Since I have no soding clue what that relates to bar and can't be bothered to convert, use the data as ye will.

If you feed it compressed air to start with it should compress it further. Try 2 in series.

75 Bar (over 1000 psi) is a very high = dangerous pressure to work with.
Horsepower is (pressure)x(flow rate), do you NEED a high flowrate AND high pressure ?

I see that Walmart, here in the USA sells a Yong Heng 30 MPa pump for $212.
Says that's 4500 PSI.
Not much capacity though.
What do you need this for? Does the application require a high flow rate?
