This question is difficult to answer, since they aren't always mentioned as individuals. In several scenes, we are simply told that elves were doing something, without being told how many.
The number of elves at Rivendell is probably not all that great, since it is described as a single house (although presumably a large one). The wood elves are rather more numerous, sending an impressive army to the lake and the mountain after the dragon is slain.
They are talented craftsmen
In the Hobbit, King Thranduil of Mirkwood, the Wood Elves' king, liked his wine from Dorwinion. His wine was also imported by the Elves of Mirkwood in barrels down the Forest River from Long lake.
If you are referring to the book "The Hobbit," we aren't told exactly. We do know that elves and dwarves had a long-standing grudge against each other. But it does seem as if the elves were trying to trap them, or at least to create an excuse for taking them prisoner. The elves in "The Hobbit" were more like the elves in Celtic folklore - silly, tricky, deceitful little fairies - than the regal, mysterious elves in "The Lord of the Rings." Legolas was a Mirkwood elf, one of the people that the dwarves encountered in "The Hobbit," and was not considered the equal of the Lorien elves.
They were tired and hungry with no food or water. At least with the elves, they were fed.Because they had lost their way in Mirkwood and were on the brink of starvation.
No. There would be some reference to the Elves and Men mixing there. But there is not. They are separate races, and though they trade, they are not related.
There are lots of creatures in The Hobbit. There are hobbits, elves, dwarves, and wizards to begin with...
In the Hobbit there is no attempt to ratify the existence of elves with the known rationale of the world. therefore they are fantasy.

Spiders, trolls and wood-elves
In The Hobbit, they are simply identified as "Wood Elves". Later, they were further identified as being Silvan Elves led by the Sindar, Thranduil (who is the father of Legolas).
The elven king in The Hobbit is the leader of the race of Elves that lived in Mirkwood.

The name of the valley is Rivendell, or in Elvish, Imladris.
The elves in "The Hobbit" did not know how the dwarves could have travelled there. They thought the barrels were all empty.
