Can someone suggest metals and gemstones to wear for a virgo born on 13th of september, to fend off bad luck , spells , attract wealth , respect , health , love  and well being

Here are some suggestions.
For Protection the use of Moonstone is suggested and for help with negative energies is the use of Hematite not the new stuff called Hemalike with is magnetic. For Relaxation the use of Jasper is suggested.
For Stress the use of Silver is suggested, even though you didn't ask about this one.
Now for the attracting wealth should be the attraction of prosperity which includes money and is not as limiting as attracting wealth the use of Jade, and it being a green stone is also good for health.
For well being the use of Moss Agate or a nice soft color in an Agate,
Now as far as self respect you will have to undergo a self worth change by using possible a Rose Quartz, again the use of Hematite,  and Galena.
Here is one added as it seems appropriate would be Psychic Protection which suggests the use of  A basic black Obsidian or an Apache tear or possibly Black Tourmaline
This is all that comes to me at the time I know there are others just as good.
The use of silver is considered the straight and truth way the over the use of gold which when overused is showing greed.
The choice is yours just use your feelings when selecting the correct stone.
Hope this help you.

Your birth stones would be Sapphire, Carnelian and Citrine.  Citrine is one of the best for attracting wealth and abundance  Rose Quartz for love, and for protection you really can't beat Black Tourmaline (Schorl) or Black Obsidian.

Do you have any crystals already? Some of them might work
