The lamps are from the 1920's or so, and are not really worth much (I got one of mine for free, and I paid 15$ for the other one). The one with the milk glass shade is probably a "Mogul base" lamp, which uses a very large light bulb with 3 settings (100,200,300w) these can be found at almost all hardware stores for around 5$ or less. Wal-Mart even carries them.
The bed frames look old, and appear to be in great shape. I don't know the age, but I'd say they're pre-1950's? I have no idea how much those might fetch, but new comparable quality beds would be over 300-500$-ish.
The chairs need work, but are decently made older chairs. Not really worth much. If they were fancy pressed-backs or something really ornate/mahogany they'd be worth money, but reasonably, you'd get 10-20$ each as-is.
That one dresser though! OMG. It might not look like much, but it's definitely old, collectible, and could be worth quite a bit. It has the original finish and old mirror (very desirable to antiques buffs/purists like me), and the turned corner decorations are an early feature. It looks like it could be mahogany? Possibly with dovetailed drawers? The style almost looks like it could be as old as the 1840's but I suspect that its probably not quite that old. Probably more like 1860-70s. Price would depend on where you sell it, and if it's the "real deal" and not a cheaper, later repro. I'd never part with this one, since it's exactly the kind of piece I'd buy, but that's just my 2 cents.
The next one is a fairly typical, well made piece from around the 1900's. Looks like 1/4 sawn oak? Very simple, and it would appeal to a bunch of people since it's so basic and non-fussy. If you list it locally, I'd say you could maybe get up to 200$ for it? I'd keep it since it matches your woodwork.
The next one, with the fancy book-matched burled walnut veneer is a typical 1920's piece, made with various woods, and stained to look like walnut. I just got a similarly built piece (an old gramophone cabinet that my dad was getting rid of). My bedroom set is a similar style, but in solid walnut (rather than veneers). Generally not all that valuable, but a good, sturdy (and nice looking) piece of furniture.
Heaters: Dunno. I have no knowledge on these. They might be collectible, but I have no idea.
