It all depends on what your level in magic is, and if you are casting the high alch or low alch spell. If I were you I'd use a runescape calculator. Here are 2 calculators below I like to use. I hope you find this useful

No, you still do lose a bit.
You'll only alchemize one noted item per spell cast of High or Low Alchemy.
I recommend high alching items like maple longbows (u) or yew longbows because when you alch them they gives you more coins than if you sold them.
To be honest with you, you shouldn't really lo-alch anything since it would be a waste of runes or/and cash spent on those runes, unless you make platebodies steel+ yourself, then low alch them.
I think you can alch it and get profit.
No, any item gives the same exp.
It doesn't matter where you alch, just alch anywhere: If you want something to watch whilst you alch: Go Castle wars or a place like that. If you want peace and quiet: Go to a place like Mos' Le Harmless, or the elven place, where not many people have access to. If you want someone to talk to, visit a friend or go to a POH and do your alching.
You cannot alch a Dungeoneering item.
