When you have used the "Group By" right-click menu item on the Peak Areas graph to group the replicates by a replicate annotation such as "Condition", there is no way to change the order that those appear in the Peak Areas graph: the annotation values will always be sorted alphabetically.
If you would prefer them to appear in a different order, we would recommend that you change the names of the conditions (e.g. "1_NF", "2_ICM", "3_NICM").
If you have not grouped the replicates, so you are displaying one bar per replicate, you can use the "Order" right-click menu item to choose different orderings.
If you have chosen "Order > Document", then you can change the ordering of replicates using the "Move Up" and "Move Down" buttons at "Edit > Manage Results".
If you would like to learn about comparing peptide quantities between groups of replicates we would recommend that you look at the Group Comparison tutorial:
