Yes you can, and the pressure will need to be set afterwards, some boilers have an inbuilt filling link, so if you dont see the flexi pipe and tap/s under the boiler, give make of boiler so we can tell you where the integral link is and how to use it.

In short - yes you can, and it does sound like you do need to bleed them. There will be a bleed valve at the top of the radiator which you can turn (might need to get a wee key for this), which will release the air.
When the combi system was installed they will have put in the correct amount of water to keep the system pressurised. So by taking air out of the system you will reduce the pressure in it. In the combi boiler there will be a way of putting water into the system to replace the air you have taken out. You do have to be careful that when doing this you don't over-pressurise the system (normally 1.5 bar is the maximum). It is a fairly straight forward process, just take care.
I have a combi boiler & heating system and do from time to time bleed the air out, this is nothing unusual so no need to worry.

I had a large cold part at the top of a rad after we had the new combi fitted. So merrily went ahead an bled it. No probs, week later I did it another time and then there was no heating or hot water. We had to represurise the system then. Whoops.....only took a minute to fix it but I have a hubby who knows how! But to be honest since then we never have had to do it again.

Yes, all radiators need bleeding sometimes.
(top the pressure to the same level (between1 and 1.2 bar) as before you started, for optimum performance.
Who ever told you not to touch the settings,
was:-
A, a lie to con you, or
B, knows you well and thinks you will mes up the system if you touch it.

yes you can bleed them , start at the furthest one, and so then keep checking the pressure bar on your combi ittl need topping up to about 1. 5 , or 2 even have the heating on to get best result, giv me ten pls

to bleed combi rads. switch off heating. check pressure gauge on boiler front. connect filling loop to system if not connected. turn on valve allow pressure to build to 1 to 1.5 bar. turn off filling loop. bleed all rads till water comes out. check pressure gauge fill to 1 to 1.5 bar. if you try to bleed with heating on you may suck air into system.

its straightforward bleed as per normal but you must adjust the pressure again as you will have let water out of the system

yes, but you will need to top up the boiler with water.
