We are wanting to remove our basement stair closet in hopes of opening up the room. We took down the walls and are wondering if any of these posts are load bearing. We know the house is resting on the two red metal posts in the middle but are questioning if we are able to removed the studs around. My goal is to make a floating staircase and turn the two metal posts into wooden beams.

If those are bolts, they are bearing walls and you would have had a fair amount of structure work in the floor system to remove them.
The bearing walls have a footing and you can see that the non bearing walls can move with the slab.

thanks for your response I added some close up photos they are nails not blots. Two of them look like they could be nailed into the ground I posted a picture the rest dont really seem to do anything besides support the drywall that used to be there.

You would have to remove some drywall to see for sure.
When you don't need the walls there is a beam or double joists from the beam to the outside wall on both sides

When building it is cheaper to add the walls below so that is the usual.

You should have double trimmers on each side of the stair, which run parallel to the stair and rest on the outer wall and two beams supported by the steel posts. So most likely the walls are non-bearing, verify.
The posts are offset, so it will look hokey to have the columns exposed under an open stair.

The photo's in post #3 indicate that they are "Float Walls" . The intent is to allow the slab to move up or down without impacting the structure above.
They are used very frequently in my area. If they are indeed Float walls they cannot be "Load Bearing".
If there is a gap between the board on the concrete and the bottomplate of the wall for the entire length they are simply "Float walls". They can be removed without issue.

Lets look at the hints.
Some walls a floating and some are not.
Some walls are newer built to square it out for a door.
If when building the house and putting the required framing in the floor would you then build non floating walls beside it?
Double plate at bottom of wall so bolts may be hidden.
The framing may be there, any one want to guarantee it?

Cut some drywall above the bottom step.
You will be looking for a double joist over the wall that reached the exterior wall.
