Re:
The Oil Bible will answer your question.
Ask your friend to check for leaks rather than relying on top-ups, as the consequences could be quite costly if ignored.

Re:
I wouldn't do it, but am old school. According to the Oil Bible it's OK to mix new oils.

Re:
Don't mix oils, they could have different viscosity which would not work well in an engine.
Be good if your friend could find out what the dealer used and then match it.
If it's only just low of the full mark, I wouldn't even bother.

Re: Top up with mixed oil?
If, as you say, the oil level is below the minimum marker, then if you need to travel before finding a vendor of the correct grade oil - then top it up with what you have at hand.
Any oil is better than no oil.
As you've hit the minimum oil level in the sump, it may be safe to assume that (a) it has been a while between oil changes , and (b) It is not a brand new car under dealer service warranty requirements.
If the car needs a top-up to get an idea of oil consumption per thousand Km, and it was serviced recently, buy a 4 litre container & top it up with the recommended grade shown in the manual. The brand matters much less than the grade specification.
Everyone who sells oil has a booklet or chart which states the recommended viscosity for the make and model of most vehicles.
Rule of thumb is to use the best oil reasonably economically available which fulfills or exceeds the oil standards (shown by codes on the container) in a newish motor.
On older motors - not much point in greatly exceeding the standard with lighter (but more advanced) oils than they were designed to use. Might just end up with a lovely bore but oily plugs and an elegant plume of vapour trailing expensively behind.

Re:
Tony,
Brand does not matter too much, but viscosity does. As to synthetic compared to mineral well that's definitely a no no.
If in doubt, drain the oil and put new stuff in, that way your sure.
How low does the level read on the dipstick, show us a photo of the dipstick.
