Well, I think you should get them out from under the bench, put them into working order and use them!
They are under-appreciated by many people, so regarded as almost disposable. They won't make you rich, but they can make you happier.
It's hard to be certain from the picture, but it looks like you have the standard trio of bench planes - jack, try and smoother. You also have a plough, and possibly a sash fillister (at the back) - but it might be another plough.
In the box you have at least one rebate plane (at the back with the nice snail shell escapement) and some moulding planes. They are most likely to include hollows and rounds (the commonest and most useful moulding planes) and possibly some sash moulders and some beads.
You will need to get the rust off the irons and sharpen them, and make a new wedge or two, but it's surprising what can be rescued with some turps, linseed oil and tlc.
There are lots of restoration threads on here - for example, this was a basket case I put back into use, probably similar to yours:

Edit: that's not a rebate plane, it's a moulding plane where someone has modified the escapement by carving a chunk out of it.
