The iron from wall of iron can not be used to make things. The spell specifically says so.
Mage hand has a duration of Concentration. You can't cast another spell while concentrating to maintain such a spell. Casting another spell would end mage hand.
Magic missile can not be used to hammer anything - it can't target objects, only creatures.
instead of just nay saying how about you present other options?
The only option that comes close to what you want is Fabricate. You must still supply the raw material though and the quality of the output is subject to Craft checks.
One route would be to make magical tools. So you have a forge that channels elemental fire to the temperature the smith commands, a quenching barrel that removes heat at a controlled rate, a golem driven hammer, that sort of thing.

Those are just magic driven versions of standard crafting tools.
What the poster seems to want to be able to do is to craft items and weapons without lifting a finger, save for the casting of a single spell. I've already given him the closest answer for that request, above.

Just pointing out some of the thing you were trying to do won't work.
There are still other options. Earth elemental miners, fire elementals to power your forges. Water elementals for quenching. Unseen servant can replace mage hand for lifting and holding the item (no tools necessary - the servant can only be harmed by area attacks, and a hot chunk of iron isn't an area attack).
But trying to do this with multiple spells is inefficient and needlessly complicated when all of the crafting can be done with a single 5th level spell (fabricate).
Magical tools exist. There is probably a spell to improve your Craft check.
i am sure the iron shards from an iron wall can be melted down and used in the process of making iron ingots.
You would be wrong. The spell specifically says the iron can not be used to make other items or sold. Probably specifically because that was an abused option in 3.5 D&D.
Like any iron wall, this wall is subject to rust, perforation, and other natural phenomena. Iron created by this spell is not suitable for use in the creation of other objects and cannot be sold.
Are you trying to create a set of houserules for making extra-magic magic items, or what? 'Cause by RAW a +1 flaming longsword is a +1 flaming longsword however you make it.
sure you can wish for a magic item or fabricate a poorly made item. those are the quick and easy way of doing something. but to create something with magic should take time and be worth that time.
Fabricate can make more than poorly made items. Quality of the finished item depends on the quality of the raw materials, and items requiring a high degree of craftsmanship can be made if you also succeed on a Craft check.
I second what Fuzzy-Wuzzy said. Just what is it you are trying to do?
Are you trying to find a highly magical way to make mundane items? If so, why? Why would anyone put that much effort into making just another mundane sword?
Are you trying to find a way to forge a magical item? The standard item creation feats can cover that. Just say the process involves "magical forging" instead of however you describe normal magical item crafting (a lot of chanting/praying, magical dusts, or whatever). The Master Craftsman feat combined with the appropriate magical item creation feat also covers this - you forge the item as normal for Craft, then enchant it. Again, this can be described as all one magical forging task.
Crafter's fortune + fabricate.
As long as you have at least a +5 Int modifier (16 Int at 1st level, +1 Int at 4th level, +1 Int at 8th level, headband of vast intelligence +2), you don't even need any ranks in the appropriate Craft skill to make masterwork items.
Unless you want to make the items without having any raw materials. Major creation can conjure a suit of armor or weapon lasting 1 hour per level (as long as it's not adamantine, alchemical silver, etc.); using crafter's fortune to make masterwork versions, as well.
If you mean using blasting spells in place of a normal forge, why? It's like trying to nail a hook on a wall for a picture frame using a sledgehammer.
do you think Prestidigitation can be used to sharpen or shape the blade on a dull sword?
No. Or more precisely, maybe, but for no more than an hour. After that it would go back to how it was before.
Prestidigitations are minor tricks that novice spellcasters use for practice. Once cast, a prestidigitation spell enables you to perform simple magical effects for 1 hour. The effects are minor and have severe limitations. A prestidigitation can slowly lift 1 pound of material. It can color, clean, or soil items in a 1-foot cube each round. It can chill, warm, or flavor 1 pound of nonliving material. It cannot deal damage or affect the concentration of spellcasters. Prestidigitation can create small objects, but they look crude and artificial. The materials created by a prestidigitation spell are extremely fragile, and they cannot be used as tools, weapons, or spell components. Finally, prestidigitation lacks the power to duplicate any other spell effects. Any actual change to an object (beyond just moving, cleaning, or soiling it) persists only 1 hour.
Many smiths put their mark on a blade to identify it. Arcane mark can do the same.
Keen edge temporarily improves a piercing or slashing weapons critical threat range. You could probably say it also sharpens the weapon at the same time (but with no mechanical effect).
Mending won't sharpen the blade the first time, but it could possibly help maintain that sharpness (as well as fixing any minor wear). Anyone with a weapon should be doing some maintenance as part of their daily down time, and a spellcasting character with a weapon could use this spell for that purpose.
darn about Prestidigitation.
If you use presti as a poor man's telekinesis, you could use it to move a whetstone up and down the blade, sharpening it. I think that's about as close as you can get.
I would have no objection if one of my players wanted to use spells to have a role in the crafting of an item. However, I would still require the craft roll to take place as normal.
Having had a moment to think about it, I might even require spells to be used in the crafting of a powerful magic item to add some flavour. The craft skill and perhaps spellcraft would be required if I went this route.
