There's no doubt about it, figs are tough, and they'll probably *survive* in that position, they most certainly are not likely to thrive.
Your original photo shows all the trees in the darkest part of the room, with very little light in evidence.... hence my concern.
I hate getting technical, but this lack of light can be explained by the diagram below. A plant on the end of the tv cabinet nearest the big window will have a much better chance of thriving, rather than being 3 metres further away from that source.
The sheer curtain will also be stopping some of the light from reaching your trees.
