Battery on my laptop is 4%, I don't have original power supply cable at the moment and I have some work to do.
Is it safe to ask a friend to give me his power cable from another type of laptop?
What parameters to look for to see if this is possible?

Same power ( voltage and Amps ) Well its doesnt have to be perfect but similar.. As an example (19.5V - 7.7A) 20V - 7.8A is fine.. Obviously the power adapter to connect should fit / be the same | |||

One size does not fit all. Buy something like the thing at picture below (would replace to CC version later), pick a matching connector, set a correct voltage. Lower power (e.g. 60W instead of 90W) is OK, just the battery charge time will raise. Same for higher (used to feed 30W netbook with 110W supply). Voltage should be the same!

My Dell D510 is OK with another Dell power supply. Original was 19.5v with 3.3 amp output. The 'extra' power supply is 19.5v with 4.6 amp output. Your mileage may vary. Take pictures of your laptop on fire if it doesn't work out, and let us know. Since, I'm only supplying a single data point. My guess is, that you can probably be within about 0.5v tolerance and 50% of the amp output... but I"m only guessing on that. Oh yeah, you'll find that the physical connector varies among manufacturers, so you'll need a 100% match there. | |||
