You can enter the intersection - when you don't need to stop on a crosswalk / zebra / official cyclist crossing
There's no limit to the number of cars that are allowed onto an intersection
Any number that can fit
The deal is that you can't impede cross traffic in doing so
So you MUST clear the intersection before cross traffic arrives
To turn left, you MUST use the leftmost lane
If more than one lane is indicated using arrows pointing left, either on the ground or on a sign

, you can use any of these lanes
To make a 180° turn, you obviously use the leftmost lane in any situation
With multiple lanes going left, aim for the according lane on the road you want to go into
Wherever there's less lanes on the road you turn into than on the one you leave, use the rightmost lane that is allowed to turn left and make the turn as wide as possible
(meaning you'll be coming from the right if there's a collision ...)
As for the term "unprotected turn" in a Belgian situation:
Legally, there is NO certainty that 3 coloured arrows indicate a protected turn
A single green arrow on the opposite side of the intersection does mean oncoming traffic has red, and could be considered a protected turn
But you may still encounter cyclists and pedestrians wo are following the road you're about to leave ...
