Figure 1 represents a molecule of Aderoxal
Figure 2 shows the complete 1H-NMR graph for a molecule of Axerol. Since there is a peak at 4.8 ppm, this states that Aderoxal is in D2O, which causes hydrogens on carboxylic acids and hydroxyl groups to not be shown, along with phosphate groups that act like a hydrogen that is part of a hydroxyl group in D2O.
Figure 3 shows a single peak at about 2.45 ppm. This peak correlates to the methyl group on the benzene ring because hydrogens that are near proximity to a benzene ring are at a range of 2.1-2.3 ppm. This peak is deshielded because it is also in close proximity to an electronegative molecule, in this case Nitrogen. The side small peek is a result to an impurity that may be present.

Figure 4 shows a doublet at 5.1 ppm. This is inconsistent since you would expect a singlet in this range. This would correspond to the CH2 group off of the benzene ring. A single peak is expected since it cannot couple with any other hydrogen. This inconsistence with a doublet could be caused to a malfunction with the NMR machine.
Figure 5 shows a skewed singlet with a minor impurity. The single peak at 7.7 ppm represents a hydrogen on a benzene ring. This is consistent since the normal range for hydrogens on a benzene ring is 7-8 ppm.
Figure 6 shows a single peak at about 10.4 ppm. This peak corresponds to a hydrogen in an aldehyde. The normal range for an aldehyde is 9-10 ppm. This peaks falls in the normal range of an aldehyde, but it slightly more deshielded.
