The suit is too big in the shoulders (hard to fix) and too long in the sleeves. Also, the drape of the pants is wrong in a way that is best left for a tailor to figure out.By the way, the shirt color is too dark for that suit.
The first pair can be worn with chinos that aren't black. However, it should not be worn to a typical workplace. It is too showy.
The second pair can be worn with chinos, shorts, etc. in colors such as brown and pastel and also with blue or white denim.

The jacket is too small in various ways (including length). The pants, as already, noted are too tight. The suit cannot be tailored to fit properly. That sales associate should be avoided.
For more unusual colors (such as green), one is a reasonable maximum and beyond two is excessive. Per season. There's no reason to use more than one henley in any month or so. Solid orange generally requires a slim frame and dark hair. Don't forget patterns and fabric variety. Also, chest pocket styles can and should vary.
In cold weather, sweaters can be used to get more out of shirts (variety).
That has too much shoulder padding. It probably needs a higher buttoning point, also. The jacket is a bit big in the waist as well. The pants are too long. Basically, try again with a different suit possibly advertised as having "natural shoulders."
The suit jacket on the right is too small. Perhaps the darker jacket could be taken in a little. Both jackets should show shirt cuff. Both pairs of pants have a problem around the leg opening - probably too too long and maybe slightly narrow.
